Can't reproduce this on Linux.

Nor I, on Windows. Compiled and ran fine in both DMD 0.142 and 0.144.

Weird. It even crashes DMD if I remove the stdio import and printf call, which should eliminate Ares as the cause.  This is with 0.144 for me. To me sure it wasn't a UTF issue, I retyped a trimmed down example into a different file.  It seems like it's happening if I pass a pointer or class reference to a vararg function:

void ptype( ... ) {}

void main()
{
    void fn() {}

    ptype( &fn );
}

I'll reinstall DMD and go from there.


Sean

I was wrong, Ares is the cause.  It appears that DMD has begun to require TypeInfo classes to be declared in object.d.  I'll fix it on my end.
