Seems unlikely to me.

The file is first loaded (mostly) as before; then all objects from the
hot section are copied to a MPS managed region.  Finally the hot section
is discarded.

My hypothesis is that discard_dump is the problem.  The hot section
probably contains something that isn't properly copied and
dump_discard_mem seems to be a bit different on Windows.  Why it even
works on Linux is a mystery to me :-).
