@rosswhitfield I suppose you do not know anything more specific? I just ran that test 10000 times without failure on Ubuntu 16.04.

[rosswhitfield]

Nope, just that it seems to fails every time on Ubuntu 14.04.

Might be similar to this: google/benchmark#67 (comment).
Are we linking pthread on Ubuntu 14.04?

Related bug report for gcc: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60662, but this is not really giving a solution.
I can reproduce this in a 14.04 VM. Linking with -lpthread does not fix it though.
