This is going to be tricky to figure out.

phlptp commented 2 years ago

@nightlark any suggestions how we go about debugging this?

nightlark commented 2 years ago

Can you get a copy of MATLAB installed in a Linux VM or system that replicates the error? Maybe something with threading, or similar to the Python segfault when importing matplotlib in a different order?

phlptp commented 2 years ago

I don't think it is related to the python matplotlib stuff. I might try on the HPC systems see if that has a similar issue on those platforms.

phlptp commented 2 years ago

The build on the CI system is now passing. So that is a good sign, so the original source of the error is resolved.

If anyone encounters this issue with a release newer than 3.3.0 please file a new issue
