now I did do

/var/tmp/portage/sys-devel/llvm-3.1-r2/work/llvm-3.1.src/lib/Target/X86/Release/X86ELFWriterInfo.o
-wrapper gdb,--args
and what happened was

then I got Program received signal SIGSEGV, Segmentation fault.
(gdb) bt

without the debug-options I would get
X86ELFWriterInfo.cpp: In Elementfunktion ��virtual long int

hope this helps
