It doesn't seem to be caused by any infinite loops, DMD just simply
runs out of memory. I've enabled some printf's and created a log file:

dmd -v -c _enum.d -I..\..\..\ > log.txt

The module names might seem familiar because it's a D wrapper around
the DMD codebase.
That's about 52KSLOC for the wrapper. Why that many lines? Because
there's setters/getters for non-pod fields, externs for functions and
for the implementation of cross-language polymorphism. I've had about
one year of work and I have a few things left to implement to make the
generator properly usable (things like re-exposing template instances
and merging them to D templates, and marking which functions assume
the calling code has memory ownership, which would reduce and
eliminate memory leaks).

I don't think this is fixable without changing when DMD releases
memory. Since every other usable D compiler is based on the DMD
front-end this is pretty much a dead-end for my codegenerator. :/
