stress_tests fail sporadically with the error:
'An invalid signature or a tampering detection should be the only
reasons of the verification failing. Status returned:
PsaErrorInvalidArgument.'
The verification signature should not be failing with PsaErrorInvalidArgument for invalid signatures. So there may be a problem with either threading or a bug in Mbed Crypto. This bug is causing several sporadic test failures in our CI, as the invalid signatures are random.
Please see opened issue #738
