The result depends on some OS conditions (it reproduced pretty well

And I can confirm that the Assert is not observed anymore (with the sleep
added after CloseHandle(childinfo->procHandle)).
Thanks for confirming. Pushed earlier today.
Do you know how it fails in non-assert builds, without the fix?
I've replaced the Assert with 'if (!...) elog(...)' and got (with a non-assert
build):
t/099_check-pids.pl .. ok
All tests successful.
Files=1, Tests=1, 67 wallclock secs ( 0.03 usr + 0.00 sys = 0.03 CPU)

So at least with my test script that doesn't lead to a crash or something.
Best regards,
