Apologies if that's obvious and you've already checked that: emacs gets created as a dumpfile of temacs during build, so if peflags moves the heap retroactively thereafter I can't see how it's going to work since part of the heap is where it was during dumping and the rest is, well, somewhere else. I'd look at the build process first before suspecting the sources — I would assume that temacs must also be made large address aware and that it right now just isn't. There may still be workarounds that aren't needed anymore and bad assumptions about how the memory map looks like in Cygwin.
