commit a40beece477f72d591491cacd79c7d5d43c3cef6
Author: Rebecca N. Palmer <rebecca_palmer at zoho.com>
Date:   Fri Feb 6 13:19:45 2015 +0000

    Add more debug output to builtin_pow test
    
    This reveals that the test "failure" is an unhandled denormal,
    which is not a bug as we don't claim to support them
