I'm seeing some test failures for unit tests for msan (check-msan)
happening in googletest, which I find weird. I'm on Arch Linux, with
r342711. Below is one type of error that I see. The full log is 416MB (!)
big. My guess is that those errors are related, but if anyone needs the
full log, I'll provide it. Here is a reduced log from the end:

What could be the problem? Thanks! :)
