So this does not happen on 64-bit Cygwin. I use both this is part of
CI testing I want to have the code compile on both, or skip the test

Recent similar failures have me think the issue is still there even on

Seeing the issue seems to be still there, when time permits, I'll see
what information I can collect regarding this issue and update this
