Another interesting case would be (but which could be handled by VRP):

return a;
}

that the #if as written in the code SHOULD be valid (by every C spec I've

struct A { std::vector a;};

struct Boom { B > > > s; };
seems to make GCC to allocate huge amounts of memory:

virtual memory exhausted: Cannot allocate memory
