Very odd bug.

I managed to narrow it down to this:

class A
{

}

class I
{
    int fork(fn);
}

alias int function(A a) fn;

The compiler crashes and gives the error in the topic title.

Here are some other "features":

It will still give the error if A is a struct.

It will still give the error if I is an interface.

It will not give the error if fn's parameter is anything other than a class or struct, i.e. if you use "int a," it compiles.

It will not give the error if you change "alias" to "typedef."

And this takes the cake: it will not give the error if you move the function alias to before the class I definition.

Forgot to mention - this error only happens when the -g compiler switch is used.  I came across this when I tried to add debug info to one of my projects, and I got this very strange error.

The problem is the forward reference to fn. I've fixed the compiler now to detect it.
