I can't reproduce.  Can you modify the ebuild to pass `epytest -s tests` locally, and see whether it gives you a specific error?

[Comment 3 Agostino Sarubbo 2023-05-07 08:56:41 UTC]

It looks like there is an assertion failure on libffi:

Can reproduce with libffi[debug]

[Comment 5 Michał Górny 2023-05-07 11:49:04 UTC]

Well, this package is using ctypes, so either it's a bug in dev-lang/python or libffi itself, I guess.  Or perhaps, a wrong use of ctypes that triggers directly in libffi instead of being caught by CPython?

Only happens with pypy3 that I can see.

Reported to pypy first at https://foss.heptapod.net/pypy/pypy/-/issues/3933.
