The debugging doesn't work with gdb and for example Intel vtune profiler crashes when trying to read the debug info. I wonder why gdb doesn't complain of missing debug info when omitting the -g flag.

On linux things seem to work fine.

Hi Mikko!

This sounds like a LLVM problem placing the debug info in the wrong location.
I try to check this with LLVM 3.4 (the binary distribution is compiled with LLVM 3.3).
