Thanks.

I think we need to try reproducing this on a Posix host before we can
conclude the bug is fixed.  The original problem was reported on
GNU/Linux, AFAICT, and the machinery used on Windows for communicating
with subprocesses is very different from that used on Unix.

Would someone please try reproducing this on GNU or Unix system?

TIA
