Probably memory usage for the PCH changed between releases.

If this is an old problem, is it really a regression then?

(In reply to comment #3)
 I suspect PCH on mingw might simply not work reliably.

Which means this is a host issue rather than a target one :).

Yeah, this is an old issue about fixed sized memory arena for .pch in
implementation of mingw here. Some of this stuff would be better done via
generic malloc/realloc instead of trying to emulate mmap here via file-mapping.
