[hash] Work around g++ bug?!

I kid you not. Revert this and see src/test-map loop forever
eating your memory freezing your maching.
In this loop:
{
hb_hashmap_t<int, int> m0;
hb_hashmap_t<std::string, int> m1;
hb_hashmap_t<int, std::string> m2;
hb_hashmap_t<std::string, std::string> m3;
std::string s;
for (unsigned i = 1; i < 1000; i++)
{
s += "x";
m0.set (i, i);
m1.set (s, i);
m2.set (i, s);
m3.set (s, s);
}
}
i will not stop at 1000 and just keeps going. If you figure out
what's going on, please enlighten me!
