           Summary: not possible to call explicit destructor of
                    std::string
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jwillemsen@remedy.nl


We want to use C++0x unions with a std::string as member (see for example
http://www2.research.att.com/~bs/C++0xFAQ.html#unions). At the moment we want
to call the ~string we get an error.

Reproducer:

#include <string>

int main ()
{
        std::string s;
        s.~string();
        return 0;
}
