Can't reproduce, given this test reads environment I assume it's something to do with what's set on the tinderbox.

I'll try to figure it out but environment file would help

[Comment 4 Ionen Wolkens 2021-10-22 07:08:04 UTC]

Can't confirm if really the cause without env file, but one way to reproduce is to have a variable that expand beyond max possible arguments.

e.g.
export A=$(for ((i=0;i<3000;i++)); do echo a; done)
pytest -v "tests/unit/commands/test_userscripts.py::test_custom_env[_POSIXUserscriptRunner]"

It additionally need to be sorted before Q (the QUTE_ variables it tests for), i.e. Z=... rather than A= won't fail.

I don't consider this to be much of a real world case, so I'll just skip the test.
