           Summary: push_back() of std::list works without argument
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: peter dot klotz at aon dot at
                CC: gcc-bugs at gcc dot gnu dot org
  GCC host triplet: i686 linux gnu

#include <list>
#include <string>

int main(void)
{
    std::list<std::string> l;
    l.push_back();
    return 0;
}

The above program compiles although the C++ standard only mentions
void push_back(const T& x)
for std::list (23.2.2, p.475).
