Are you absolutely sure that's the line? The compiler is claiming that
it can't call the hashing function with an argument of type A (probably
means there's no appropriate overload). The puzzling thing is that it
wants to call the hasher because it's resizing the hashtable, and it's
doing that in response to a call to hash_set::insert - allegedly
directly from your code.
I can't track the error beyond this. The standard library in my GCC
3.4.4 is quite different.
