help debugging segfault with alienarena 7.32



I need to rebuild alienarena for all targets due to a security issue, so
I decided to update to 7.32, but unfortunately, the 7.32 build segfaults
immediately on Fedora 12 (x86_64), and gdb isn't much help (gdb output
is at the bottom).

Now, it is worth noting that the alienarena client does dlopen the
openal-soft library by name:

   const char libopenal_name[] = "libopenal.so.1.9.563";
   void *dynlib;

   dynlib = dlopen( libopenal_name, RTLD_LAZY | RTLD_GLOBAL );

However, I can't seem to find a breakpoint that gdb will hit before the
app segfaults, and printfs never get triggered.

Any and all help is appreciated, as I'd like to get this fixed before F-12.
