Under some conditions, gdb 6.8.50.20081120 backtrace crashes. See valgrind output below. I think the problem in cplus_demangle_print_callback on some template methods (for instance boost bind calls)
The solution is installing gdb-6.8.50.20090818-16.1.i586.rpm (from channel http://download.opensuse.org/repositories/devel:/gcc/openSUS E_11.1)
