Package: libapache2-mod-php4
Version: 4:4.4.2-1+b1
Severity: important

Hi PHP maintainers,
we are seeing segmentation faults on webservers running a PHP4
application (horde/imp clone). They are reproducible after about
two hours of server uptime und serving some 50,000 requests and
appear only under high load. We let apache dump core, the backtrace 
is identical for each core file so we can assume that we are observing
only one single kind of failure. We rebuilt libapache2-mod-php4 with 
full debugging symbols (CFLAGS += -ggdb) to obtain the attached 
backtrace. Please be aware that packages listed below have custom 
revision numbers which is because of our release process and does not
include source changes. I am attaching php.ini as well. Used extensions 
have following versions:

  php4-curl     4:4.4.2-1+b1
  php4-imap     4:5.1.2-1
  php4-mhash    4:4.4.2-1+b1
  php4-pgsql    4:4.4.2-1+b1
  php4-ldap     4:4.4.2-1+b1
  APC           3.0.8 self compiled

Please don't hesitate to contact me for further information.
Thanks and best wishes,
  Jörg

[PHP]

;;;;;;;;;;;
; WARNING ;
;;;;;;;;;;;
; This is the default settings file for new PHP installations.
; By default, PHP installs itself with a configuration suitable for
; development purposes, and *NOT* for production purposes.
; For several security-oriented considerations that should be taken
; before going online with your site, please consult php.ini-recommended
; and http://php.net/manual/en/security.php.


;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior.  In order for PHP to
; read it, it must be named 'php.ini'.  PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory.  The
; path in which the php.ini file is looked for can be overridden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple.  Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; |        bitwise OR
; &        bitwise AND
; ~        bitwise NOT
; !        boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
;  foo =         ; sets foo to an empty string
;  foo = none    ; sets foo to an empty string
;  foo = "none"  ; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

; Language Options ;
;;;;;;;;;;;;;;;;;;;;

; Enable the PHP scripting language engine under Apache.
engine = On

; Allow the <? tag.  Otherwise, only <?php and <script> tags are recognized.  
; NOTE: Using short tags should be avoided when developing applications or
; libraries that are meant for redistribution, or deployment on PHP
; servers which are not under your control, because short tags may not
; be supported on the target server. For portable, redistributable code,
; be sure not to use short tags.

; Output buffering allows you to send header lines (including cookies) even
; after you send body content, at the price of slowing PHP's output layer a
; bit.  You can enable output buffering during runtime by calling the output
; buffering functions.  You can also enable output buffering for all files by
; setting this directive to On.  If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).
output_buffering = Off

; You can redirect all of the output of your scripts to a function.  For
; example, if you set output_handler to "mb_output_handler", character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
;       directive. Instead, explicitly set the output handler using ob_start().
;       Using this ini directive may cause problems unless you know what script 
;       is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
;       and you cannot use both "ob_gzhandler" and "zlib.output_compression". 
;output_handler =

; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary due to nature of compression. PHP 
;       outputs chunks that are few hundreds bytes each as a result of 
;       compression. If you prefer a larger chunk size for better 
;       performance, enable output_buffering in addition.
; Note: You need to use zlib.output_handler instead of the standard
;       output_handler, or otherwise the output will be corrupted.
zlib.output_compression = Off

; You cannot specify additional output handlers if zlib.output_compression
; is activated here. This setting does the same as output_handler but in
; a different order.
;zlib.output_handler =

; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block.  This is equivalent to calling the
; PHP function flush() after each and every call to print() or echo() and each
; and every HTML block.  Turning this option on has serious performance
; implications and is generally recommended for debugging purposes only.
implicit_flush = Off

; The unserialize callback function will be called (with the undefined class'
; name as parameter), if the unserializer finds an undefined class
; which should be instanciated.
; A warning appears if the specified function is not defined, or if the

; So only set this entry, if you really want to implement such a

; Whether to enable the ability to force arguments to be passed by reference
; at function call time.  This method is deprecated and is likely to be
; unsupported in future versions of PHP/Zend.  The encouraged method of
; specifying which arguments should be passed by reference is in the function
; declaration.  You're encouraged to try and turn this option Off and make
; sure your scripts work properly with it in order to ensure they will work
; with future versions of the language (you will receive a warning each time
; you use this feature, and the argument will be passed by value instead of by
