Some compiler versions (seen with gcc 4.8.1) move the resume label after
the return statement which, of course, causes sever problems.

Can you include the assembly output?  Do you mean after the "ret"
instruction?

Reproduced now, I think it's a compiler bug... with -O2 it's even weird, &&resume points to the *first* instruction in the function.

I'll report it to GCC.
