Yeah, that's because doom3/quake4 and your system's libGL link to incompatible libgcc_s.so.1 and libstdc++.so.5.
Yeah, I knew the reason immediately after removed those. Furthermore, the faq on zerowing.idsoftware.com says: Should I replace libgcc and libstdc++ with the ones from my distro? While we haven't seen that replacing them will noticeably improve performance, on some distribution (gentoo for instance) this is known to cause crashes. At your own risks.
Now _not_ replacing them causes crash. Maybe this should be mentioned on http://www.x.org/wiki/RadeonProgram. Who can edit that page anyways? It seems quite outdated.
