Stat too good

GHC - devs mailing list

Ben,

I still get these four stat-too-good “failures” on 64-bit Linux.

Unexpected stat failures:

   /tmp/ghctest-ca0gfq/test   spaces/./perf/compiler/T13035.run  T13035 [stat too good] (normal)

   /tmp/ghctest-ca0gfq/test   spaces/./perf/compiler/T12425.run  T12425 [stat too good] (optasm)

   /tmp/ghctest-ca0gfq/test   spaces/./perf/compiler/T1969.run   T1969 [stat too good] (normal)

   /tmp/ghctest-ca0gfq/test   spaces/./perf/compiler/T9233.run   T9233 [stat too good] (normal)

Don’t you?

Simon

Just FYI: I'm on 64-bit Linux and don't see those failures (I just validated at 763f43e6d3)

Cheers,
Michal

I'm not seeing anything like this at the moment but I have seen a great
deal of variability in testsuite results recently. In fact, I had to bump the
acceptance window size of T4029 as my local machine, Harbormaster, and
the OS X build bot differed by nearly 10% in max_bytes_used.

Cheers,
