The following program fails to compile with every version of GCC 4.x I
tested (including current mainline) with
error: no match for call to '(const __gnu_cxx::hash<long long int>) (const
long
long int&)'
==== snip ====
#include <ext/hash_set>
using namespace __gnu_cxx;
typedef long long T;
void f() {
hash_set<T> t;
t.insert(1);
t.erase(1);
}
==== snip ====
The problem is that libstdc++ fails to define hash<long long>.
