The segfault was because I forgot to mark one of my new methods as "final",
and it was messing with the poffset in baseOf.

I think this is relevant to anyone mixing D and C++, not sure if its for
everyone because I'm not sure where poffset comes from. Basically if a
struct works and a class causes the compiler to segfault in baseOf when
compiling your module, its probably this.
