Cannot reproduce on my local machine, and the light mode on MFYI bot seems fine, so exclude it for now.

I can reproduce.

** INFO native: works
** INFO full mode: fails
** INFO -no_check_uninitialized: works
** INFO -no_fastpath: works
** INFO no fastpath for floating-point instrs: works

So it's something to do w/ floats. Not sure yet exactly what though.

I've re-filed this under https://code.google.com/p/chromium/issues/detail?id=377702 since this reproduces under TSan as well.

I spent some time on this in the past but forgot to update the issue: this one seemed at first to perhaps be a bug in Dr. Memory but that was a red herring as it was non-deterministic and seemed to be something inherent in the test being fragile to time dilation. Repro under TSan corroborates that.
