Bug#295194: libglib2.0-0: segfault in g_option_context_add_main_entries

[Torsten Marek]

Package: libglib2.0-0
Version: 2.6.2-1
Severity: normal

This little program makes gtk/glib segfault:
## start ##
#include <gtk/gtk.h>

int main(int argc, char** argv) 
{
    char** myargv = (char**)malloc(sizeof(char*)*3);
    int myargc = 2;
    
    myargv[0] = "test";
    myargv[1] = "-calendar";
    myargv[2] = 0;
    
    gtk_init(&myargc, &myargv);
    return 0;
}
## end ##

Backtrace:
Program received signal SIGSEGV, Segmentation fault.
0xb7b60266 in g_option_context_add_main_entries () from /usr/lib/libglib-2.0.so.0
(gdb) backtrace

#5  0x0804875d in main (argc=1, argv=0xbffff824) at checkargs.c:12

If I change "-calendar" into "--calendar", no segmentation violation takes place.
This bug occurs when running mozilla-sunbird (both prebuilt versions from mozilla.org
and cvs builds).

greetings

Torsten
