--- Comment #20 from Tom Hughes <tom@compton.nu> ---
Actually given that the return from the call will unwind the stack again that
means the caller will be accessing values below the stack pointer which is
unsafe if a signal fires as the signal may trash the stack below the stack
pointer (there's a small extra redzone below sp that is safe on x86_64 but not
on x86_32).
