Comment (by rhaas):

 Replying to [comment:3 rhaas]:
 > Hmm. This is new then. I use gfortran 4.9.2 on my (Debian) workstation
 and the test passes there (kind of unsurprising since the data was
 generated on that machine) and I also tested it on a Ubuntu VM shortly
 after the release. I'll check once more if it still passes or fails and if
 it fails, when it started to fail.

 Addendum: I tested with optimization though. Unless we are using fast-math
 with gfortran the results should not differ, but then, Fortran does not
 really guarantee any particular ordering for floating point evaluations.
 I'll test with and without optimizations.
