So it seems that updating SymPy hasn’t resolved the hang problem. So I have now added a workaround to skip the hanging test. This should at least get the tests running to completion again and producing results – the skipped test will show up as an error-ing test in the results.
Except that this isn’t the only test that runs into this problem:
- sympref
- @sym/dsolve
Forcing an error during these tests allows the project build to run to completion.
