Just addin my drop here:
Just did the same, both single and double precision, not parallel anyway.
What I get is the following:
*aurora down/gmxtest 41%* ./gmxtest.pl all
All 16 simple tests PASSED
FAILED. Check files in dec+water
1 out of 14 complex tests FAILED
All 63 kernel tests PASSED
All 45 pdb2gmx tests PASSED

*aurora down/gmxtest 42%* ./gmxtest.pl -double all

There are 5 terms to compare in the energy files
LJ (SR) step 34: -0.21167, step 34: -0.230957
Files read succesfully
Again, it looks like the same "error" that appears in the wiki... except
that the wiki mentions two error lines in there instead of one. Also, the
wiki mentions the line differently:
LJ (SR) step 34: -0.176025, step 34: -0.21167
Which, on its turn, seems quite odd. I thought the first number was the
standard one, has it changed between 3.3.2 and 3.3.3 gmxtest' beds? And can
it be that the original problems with gcc4 has vanished with the newer
versions of it?
Thanks a lot, and hope it also helps.
