--- Comment #55 from Don Lewis <truckman at FreeBSD.org> ---
It's not really repeatable at all.  I've seen a couple different clang aborts,
but they are pretty rare, and happen when building different ports each time. 
I did manage to get the proper environment set up so that I could analyze the
latest clang core files.  Here's the stack backtrace for the libreoffice
failure:

__stack_chk_fail_local() is part of the stack smash detector.  It appears that
the stack check canary is random, which might have something to do with the
failures being random ... or we're getting random stack smashes.
