Mesa-GL segfault upon library load

[Guest]

Maybe somebody can help me with this problem that started to appear with Feisty and Gutsy (but not Dapper). Since version 7.04 I can no longer use GL in some of my programs. Consider a program that does not call any GL libraries (any GL calls commented out). I link it with

gcc -g -O2 -Wall -o executable stuff.o more.o main.o -rdynamic -L/usr/lib -lgtk -lgdk -lgmodule -lglib -ldl -lm -lfftw3 -ltiff -lgdk_imlib -lGL

...segfaults before the first instruction. This means that I can not even use gdb to debug it.

- If I omit the -lGL, the program runs OK.
- If I omit the -rdynamic, the program runs OK, but I can no longer load DSOs.
- Different graphics cards (Nvidia, ATI, hardware or software driver) have the same effect.
- Different C compilers have the same effect.

Here is the gdb stack dump. Doesn't help me a whole lot:

Any help would be appreciated. Thanks!
