Failure in test_hashlib.py and test_hmac.py
I am building Python 2.6.4 on a shared server and am encountering test failures in test_hashlib.py and test_hmac.py, specifically concerning sha512. I recompiled Python with --with-pydebug and CLFAGS=CPPFLAGS="- g" and ran the tests in GDB and got the following results: GNU gdb 6.6.50.20070726-cvs Copyright (C) 2007 Free Software Foundation, Inc.
