[issue23842] SystemError: ../Objects/longobject.c:998: bad argument to internal function

[STINNER Victor]

STINNER Victor added the comment:

> return '%d:%d' % (os.major(st.st_rdev), os.minor(st.st_rdev))

Can you check if the error comes from os.major() or os.minor(), and please provide the value of st_rdev?

You can modify the unit test to catch SystemError and raise a new exception with more information.
