Hi there!
When building krb5 using Python 3.14, I discovered a test error. Python's
multiprocessing module now uses `forkserver` as the default start method
unless specified otherwise (see
https://docs.python.org/3/whatsnew/3.14.html#multiprocessing). This breaks
`src/tests/t_otp.py` when the daemon starts. A temporary fix is to force
the start method to use `fork` instead. However, this test should probably
be rewritten to respect `forkserver` instead.
All the best,
Simon
