mingw g++ problem in f14

[David L]

I tried cross compiling a c++ app with mingw in f14 and run it in wine
and it kept crashing at startup.  I stripped the app down to the small
example below and it still crashes with the output after the example.
The same test app works in fedora 12 and Ubuntu 10.10.  I haven't tried
running it under fedora 13 or in Windows instead of wine.  If I
make bar() non virtual it doesn't crash, but it's not really an option
for the original application.  Any ideas?

Thanks,

         Dave

class Foo {
  virtual void bar();
  virtual ~Foo() {;}
};

void Foo::bar()
{
}

int main()
{
  return 0;
}
