gl debugging help requested

[Tom "spot" Callaway]

I'm trying to clean up vamos (a GL realistic automotive simulator), but
while I can get it to build on my rawhide box, it segfaults upon
execution.

When I run it through gdb, it says it is segfaulting on:

0x00002aaaac0d2c0b in glGenTextures () from /usr/lib64/libGL.so.1
(gdb) bt
#0  0x00002aaaac0d2c0b in glGenTextures () from /usr/lib64/libGL.so.1

    texture_wrap=10497) at Texture_Image.cc:94
#2  0x00002aaaab581c34 in Texture_Image (this=0x7fff31cc9e30,

#5  0x00000000004023c9 in _start ()

I don't know the first thing about writing GL apps, nor has googling
imparted me with any useful tidbits.

The latest SRPM is here:

Any and all patches or advice is welcomed.

Thanks in advance,
