[ocaml5-issue] Windows failures on threadomain

[jmid]

We have also observed failures on Windows on the threadomain test combining Domains and Threads.

Here is a fresh occurrence on 5.0.0~beta1:
https://github.com/jmid/multicoretests/actions/runs/3487203320/jobs/5834552533

This exits with a weird exit code -1073741819

This was previously observed on #179 - also on the Windows 5.0.0~beta1 combination and with the same symptom of a weird exit code:
#179 (comment)

Following a discussion with @dra27, I wrote a dummy executable to trigger a segfault:

PS> .\a
PS> echo $LASTEXITCODE
-1073741819

(-1073741819 is 0xc0000005, by the way).

[dra27]

(-1073741819 is 0xc0000005, by the way).

Which is indeed access violation / segfault 👍

Saw what looks like a deadlock and a 6 hour timeout on threadomain on Windows 5.0.0+trunk - with none of the previous tests haven taken substantial amounts of time:
