That's definitely the first thing you should fix. Preferably a debug
build too. The only reason you should ever be debugging against a
release build of LLVM is if you have a Heisenbug that doesn't happen
otherwise. It's a horrible experience.

Even a release build can give you a backtrace if you attach a
debugger, though as I've said I wouldn't normally bother.

Cheers.
