problems with vtable-thunks

[Joost Kraaijeveld]

If I compile the following source with -fvtable-thunks it prints
"s.fail()", if I compile it without -fvtable-thunks it does not. Is this
a bug or is this by design? If by design, can anyone point explain it to
me (or point me to a URL).

Yes, I know strstream is depricated.


#include <iostream>
#include <strstream>

class Base
{
   public:
      Base() : ulong(10) {}
      unsigned long ulong;
};

int main(int argc, char* argv[], char* /*envp[]*/)
{
   Base base;
   std::strstream s;
   s.write(&base,sizeof(Base));
   if(s.fail())
   {
      std::cout << "s.fail()" << std::endl;
   }
   return 0;
}
