Just committed a fix for this and closed the PR.

Last I looked I couldn't reproduce.  Torvald, perhaps you could see if 
you can reproduce on your end?

I just closed this as it was an assortment of distinct failures reported 
by a variety of people on different architectures (some of which were 
already fixed).  I have suggested in the notes that individual PRs be 
filed if problems are still present.  A generic "libitm failures" PR 
doesn't help.
