No, that's unrelated. This isn't a CTFE bug, it's a bug in enums. Semantic has
not yet been run on the enum initializer.  My guess is that this is a forward
reference issue.

If you change it:

 struct foo(size_t N)  {
-     enum size_t SIZE = FooSize!N;
+     enum size_t SIZE = 0 + FooSize!N;

then you get a segfault, because the type is still NULL.

My guess is that this was exposed by my "do const-folding in CTFE" patch.
Previously these kinds of errors went undetected.
