In Debian (only change from -1 should be disabling some tests, i.e. real pandas-related failures are unlikely): mdtraj/amd64: upstream tests pass but a warning is printed to stderr, which autopkgtest counts as a fail partd/ppc64el: save/load of a plain string fails snakemake/i386: hang in test_pipes_fail statsmodels/armhf: wrong answer in TestDFMComplex These have all happened before, suggesting they're random, i.e. bugs in these packages not in pandas. (For partd, the other known instance was on a different architecture (s390x), but it looks like partd only uses pandas when it's handling pandas objects, which this test isn't.)
Thanks Rebecca. Looks like the mdtraj error is transient, passes eventually. Makes it hard to debug robustly.
From the error message "ValueError: Invalid file descriptor: -1" it looks like an actual error, so I don't want to immediately ignore it with allow-stderr. The mdtraj tests themselves pass so I guess it has something to do with shutting down pytest.
"Invalid file descriptor" suggests an object is deleted before a reference to it is removed, though strange for that to show up in a python context.
