Good, some helpful information with the runs you made.
In the crash below it made more progress it was able to allocate multiple
regions of shared memory and access them. I don't know why it would crash later.
Can you tell me all the steps with miniforge (which seems to be related to
the failure) you use? I've never used miniforge.
If I can get to an environment that reproduces the problem I can debug it
and fix it.
