Hello *,
I noticed something odd while validating the GHC 7.10 branch:
bytes allocated value is too low:
(If this is because you have improved GHC, please
update the test so that GHC doesn't regress again)
Expected T9961(normal) bytes allocated: 772510192 +/-5%
Lower bound T9961(normal) bytes allocated: 733884682
Upper bound T9961(normal) bytes allocated: 811135702
Actual T9961(normal) bytes allocated: 9766160
Deviation T9961(normal) bytes allocated: -98.7 %
*** unexpected stat test failure for T9961(normal)
...then I also ran ./validate against today's GHC HEAD, and re-ran the
T9961 test:
Expected T9961(normal) bytes allocated: 772510192 +/-5%
Lower bound T9961(normal) bytes allocated: 733884682
Upper bound T9961(normal) bytes allocated: 811135702
Actual T9961(normal) bytes allocated: 748225848
Deviation T9961(normal) bytes allocated: -3.1 %
I'm not sure if it's just the test-case being broken, or there's
something real regression between 7.10 and HEAD...
However, I don't have time to investigate this.
Cheers,
hvr
