SampleBrowser crashes (seg. faults) when using fglrx driver (for FireGL V5700)

SampleBrowser runs fine when I use open source radeon driver.

Interestingly, SampleBrowser runs fine when started from gdb (even with the fglrx driver), and using valgrind produces the following output:

Furthermore, if I download the source package (apt-get source ogre) and build Ogre from the resulting source tree using CMake (mkdir build && cd build && cmake path_to_ogre_source) SampleBrowser works as expected, so the bug is obviously introduced with packaging. Packager additional FLAGS, hardening, ...?
