[Pkg-freeciv-devel] Bug#323078: freeciv-client-gtk: Client crashes on start if (when) /usr/lib/charset.alias is missing

Sun Aug 14 16:26:05 UTC 2005

Package: freeciv-client-gtk
Version: 2.0.4-1
Severity: important

  Severity important, as I can't reproduce this bug on my work box.

  I have been trying to get myself addicted to freeciv, but failed to do
so as the client simply does not even start. Executing civclient-gtk
dumps a corefile, which is of little use.

  With DEB_BUILD_OPTIONS=debug,nostrip I get the following backtrace:
(gdb) bt
#0  0xb78f4ae3 in strlen () from /lib/tls/i686/cmov/libc.so.6
#1  0x080826c5 in mystrlcpy (dest=0x811a400 "", src=0x0, n=512)
    at ../../utility/support.c:234
#2  0x080ea76b in ui_init () at ../../../client/gui-gtk-2.0/gui_main.c:1024
#3  0x08056e3f in main (argc=1, argv=0xbffffc64)
    at ../../client/civclient.c:302

  Stracing the execution provides the actual information:
<clipped useless stuff>
futex(0xb7901aa8, FUTEX_WAKE, 2147483647) = 0
open("/usr/lib/charset.alias", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file o
r directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV (core dumped) +++

  The really weird part of the problem is that according to client
sources, charset.alias can be NULL. Also, support.c:mystrlcpy() actually
calls assert() to make sure source can not be NULL. So how is this even
possible?

  Workaround is to install package that provides charset.alias, right? 
According to packages.debian.org, *NO* package provides the file.
Viewing old bugreports from 2000-2001 imply that at some time both
fileutils and shellutils have provided the file in question.

  I have made absolutely sure that no libraries are locally built:
