Bug or what?

[Phil Lavoie via Digitalmars-d]

Ok so me and one of my colleagues have been working on some code 
at a distance. We both use dmd as the compiler. I am under 
Windows, she OSX.

It is not uncommon that she experiences more strictness in the 
type system than I do. For example, something like this does 
compile for me, but not for her:

int func(size_t i)
{
   return i;
}

It passes my compilation. She gets an error msg about implicit 
casting of uint to int. I'm just wondering... has anybody else 
experienced that and what is the expected behavior?

Thanks,
Phil
