Subject: [Bug other/13794] New: hash_set<std::string> doesn't work
X-Bugzilla-Reason: CC

List-Id: <gcc-bugs.sourceware.org>

When trying to compile the following example:

-----8<-------

#include <ext/hash_set>
#include <string>

void test() {

   __gnu_cxx::hash_set<std::string> s;
   s.insert("One");
   s.insert("Two");
   s.insert("Three");
}

-----8<-----

the compiler reports:

-----8<------
