segfault on debian

[who_ami siedziba pl]

hi!

my program gets segmentation fault on debian ( on other distros works
fine).

(gdb) info stack#0  0x404b02ff in mallopt () from /lib/libc.so.6#1
0x404af2ca in free () from /lib/libc.so.6#2  0x40047356 in g_free () from
/usr/lib/libglib-2.0.so.0#3  0x400404ac in g_list_foreach () from
/usr/lib/libglib-2.0.so.0#4  0x0807001f in load_combo () at
conffile.c:237#5  0x0806f81a in my_create_window_login () at
windows.c:1863#6  0x08050b78 in main (argc=1, argv=0xbffffae4) at
main.c:161

do you know any idea what can it be ?  ?

glib-2.2.1
debian sid/unstable current
kernel-2.5.62
