Tested with 3.6.0-0.82.gfc691d0246b9 on Windows 10 22H2 x64, the
problem
still occurs.
In my evrironmen, trial for 1 hour does not reproduce the issue.
Could you please let us know your environment, i.e. CPU, amount of
memory, and so on?
It's been reproduced in a variety of environments:
* Windows 10 22H2 x64, Intel Core i7 11700, 32 GB RAM
* Windows 10 22H2 x64, Intel Core i7 9700, 32 GB RAM
* Windows 10 22H2 x64, Intel Core i7 6700, 32 GB RAM
* Windows 7 SP1 x64, Intel Core i7 6700, 32 GB RAM
I'm surprised that you're not hitting it very quickly. The following
loop usually fails after a few iterations (rarely a hundred or so) in my
tests:
while bash -c 'true & true & wait -n || { echo 1: $?; exit 1; } && wait
-n || { echo 2: $?; exit 1; }'; do echo $((i++)); done
Thanks,
Alexey
