AFAICT, all that dip1021 is doing is make the compiler call GC.malloc/GC.free a
number of times more often than it usually does.

https://github.com/dlang/dmd/blob/master/compiler/src/dmd/ob.d

I'd consider the main trigger to be `-lowmem` - so it may well be the GC itself
that is at fault, given that git blame points to a change in `_d_newclass`,
this seems the most plausible explanation.
