Dear maintainer:

I assume this will happen randomly because the build log contains a line
saying "random seed" which is different each time.

In fact, I only have this failed build log for now, however, I wonder if the random seed
appearing in the build log would be enough to reproduce the problem.

If yes, then this will surely happen in the buildds (sooner or later,
since it's random), and according to some people, this would make the
bug to be serious. If that's the case I would recommend choosing a
fixed random seed which is known not to make the tests to fail.

Thanks.
