commit a8fc0f42e1eda2fa3393d1ea5e61322d5e07a9cd
Author: Darren Tucker <dtucker at zip.com.au>
Date:   Wed Aug 17 13:35:43 2016 +1000

    Test multiplying two long long ints.
    
    When using clang with -ftrapv or -sanitize=integer the tests would pass
    but linking would fail with "undefined reference to __mulodi4".
    Explicitly test for this before enabling -trapv.
