[cfe-dev] label problem. debug info?

[Daniel Dunbar]

This is an LLVM issue, actually I have already filed a bug for it:
http://llvm.org/bugs/show_bug.cgi?id=2075

The problem is that optimization w/ debug info is not well supported.
Using: 'llvm-ld -disable-opt ...' should solve the problem (but, of course,
disable optimization).
