Probably the packaging as I've built gcc 4.7.2 and don't have the 
problem.  I can't see a difference, ask me where to look.



$ cat t.cc
#include <stdexcept>

int main(int, char**)
{
   try {
      throw std::runtime_error( "Catch me if you can!");
   } catch(...) {
      return 0;
   }
   return 1;
}
$ g++ -m64 t.cc
$ ./a.out
$ file a.out
