[issue33627] test-complex of test_numeric_tower.test_complex() crashes intermittently on Ubuntu buildbots

STINNER Victor <vstinner at redhat.com> added the comment:

I bet that the bug comes from _decimal. Fraction is implemented in pure Python, and complex type is supposed to be simpler than the _decimal.Decimal type.

The whole mystery is why the bug only occurs in test_numeric_tower.test_complex() and why not in test_complex, test_fractions or test_decimal!? And why the bug is random.
