Under -We, PyErr_Warn raises an exception rather than printing to
stdout. That exception is clobbered by the immediately following call
to PyErr_Clear.
Since you *only* hit that branch under -We in the first place, a
second call to PyErr_WriteUnraisable should get the error to actually
print out.

Cheers,
Nick.
