             Bug #: 55728
           Summary: std::bad_function_call has misleading what() result
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: joerg.richter@pdv-fs.de


cat t.cc << EOF
#include <functional>
#include <iostream>

int main()
{
  try
  {
    std::function<void()>()();
  }
  catch( std::exception const& e )
  {
    std::cout << e.what() << std::endl;
  }
}
EOF

g++ -std=c++11 -o t t.cc
t

# gives me "std::exception"

Not wrong, but "std::bad_function_call" would have saved me some debug time.
