Sorry for the late reply, Marco.

No, there are no code differences in Cygwin based on "Home" vs.  "Pro"
vs. "Enterprise" editions.  Differences are mainly based on Windows
versions, as in W10 1803, W10 1809, etc.  Other differences in code
execution are based on workstation vs. server (evaluating scheduling
timing from registry) or stand-alone vs. domain machine (passwd/group
stuff).  Of course, even small differences in your setup (Windows
permissions, etc.) may lead to very different code execution.

If you suspect a Cygwin bug, it would be helpful to see an strace
of the crash.
