Why is throw_exception detected as returning something in the first place?

I've personally tried to force __attribute__((noreturn)) with GCC, but
it doesn't work, it says the function does return.

Looking at the code though, I can't tell what is wrong with it.
A fix to that would be appreciated. Without that, I'd personally rather
not use throw_exception.
