--- Comment #1 from Luís Ferreira <contact at lsferreira.net> ---
Along with other recursive expansions, the compiler should be able to detect
the stack overflows before exploding with stack protection mechanisms by
reading and comparing the stack size at runtime when such recursive expansions
happen.
