I'm seeing this in validate

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 T5837(normal) bytes allocated: 56782344 +/-7%

Lower bound T5837(normal) bytes allocated: 52807579

Upper bound T5837(normal) bytes allocated: 60757109

Actual T5837(normal) bytes allocated: 52424864

Deviation T5837(normal) bytes allocated: -7.7 %

*** unexpected stat test failure for T5837(normal)

This test has historically been quite unstable. I'm running a validate as we speak; I'll let you know if I can reproduce this. Cheers, - Ben
