Test case

I can't verify this on a Windows system right now, but under wine, the output
is something like:

00006FFFFFB04220
0 = 0
00006FFFFFB04220 = 00006FFFFFB042B0

Under Windows MSVCRT, the last equality should be true. Under UCRT, it's
apparently false, as UCRT appears to behave like wine (reuse file handles
starting at fd=3, but never reuse stdin, stdout, or stderr).

I'd appreciate if someone could attach the relevant logs :-)
