[New-bugs-announce] [issue22044] Premature Py_DECREF while generating a TypeError in call_tzinfo_method

[Tom Flanagan]

New submission from Tom Flanagan:

call_tzinfo_method in Modules/_datetimemodule.c:900 calls Py_DECREF(offset)
before trying to use offset to generate a TypeError message.

This causes a crash if that was the last reference to offset and Py_DECREF clears it.
