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;
}
