Ah, these two together are probably not going to work with the code as
written (even GCC errors out on similar test-cases I've tried). You're
either going to have to avoid O0 when producing a .o file or modify
the source so it works (maybe by converting the function to a macro),
but I wouldn't be surprised if you hit other issues on that route.

Cheers.
