This may be relevant, from Lib/test/test_b1.py:

        # Note: This test is expected to SEGV under Cygwin 1.3.12 or
        # earlier due to a newlib bug.  See the following mailing list
        # thread for the details:

        #     http://sources.redhat.com/ml/newlib/2002/msg00369.html

In Cygwin, malloc() was treating the size as signed which caused a
crash.  Perhaps you are experiencing something similar?  Have you
tried with the latest Cygwin?
