Package: php5-sybase
Version: 5.3.3-7+squeeze1
Severity: important

In order to test my php5 applications on Debian Squeeze, I upgraded from
Debian Lenny to Squeeze on a test machine.
Tests on Debian Squeeze have shown me that php5 causes segmentation
fault when a script try to query MS-SQL-SERVER.
I use php5-sybase (freetds-bin, freetds-common) for connect to

Actually the bug occurs when I query a row which contains a money type
column. If there isn't a money type column in the row,
the script doesnt't return segmentation fault. I have seen this when I
activated log on freetds, and freetds seem to shutdown on:
dblib.c:2141:dbconvert((nil), SYBMONEY, 0x2cfd858, 8, SYBFLT8,
0x7fffb52df1a8, 0)

I can see that a similar BUG exist on PHP: #52546
but I don't know whether this patch was integrated on the current
release of php5-sybase.

On Debian Lenny with the excatly same configuration, I have no problem.

A tsql session which query a row containing a money type value works
(Prix and Montant are money columns, yes I'm french :) )
$ tsql -S gestion -U Toto -P Toto
locale is "fr_FR at euro"
locale charset is "ISO-8859-15"
1> use Test;
2> SELECT * FROM ArticleStock WHERE Article=100 AND Site=3;
3> go
Article Site    Stock   Prix    Montant DateCreation    DateSaisie
100     3       0       242.76  0.00    2007-10-24 16:53:51 2008-07-10
(1 row affected)

I can't solve the problem for the moment and I have to stay on Debian
I can send, if necessary, two full log samples of freetds (one from
Lenny and the other from Squeeze) of the same query test.

My configuration of freetds:
# TDS protocol version
;       tds version = 4.2
# Whether to write a TDSDUMP file for diagnostic
# purposes
# (setting this to /tmp is insecure on a
# multi-user system)
;       dump file = /tmp/freetds.log
;       debug flags = 0xffff
# Command and connection timeouts
;       timeout = 10
;       connect timeout = 10
text size = 64512
host =
port = 11111
tds version = 7.0
;dump file = /tmp/freetds.log
