Your test program is faulty, you should use %p in these two printfs.

On my system, those two symbols are aliases in libGL.so:

$ nm -D /usr/lib/i386-linux-gnu/libGL.so | grep glGetDebugMessageLog
0006dc30 T glGetDebugMessageLog
0006dc30 T glGetDebugMessageLogARB

and the corrected test program prints the same address.

Back onto the main bug report, I cannot reproduce this issue. Are you
totally sure you are using mesa libGL?
