My clean build of origin/master, on 64-bit Linux is showing these failures

Unexpected failures:

   /tmp/ghctest-5_qx1p/test   spaces/./pmcheck/should_compile/T11195.run   T11195 [exit code non-0] (normal)

Unexpected stat failures:

   /tmp/ghctest-5_qx1p/test   spaces/./perf/compiler/T5837.run   T5837 [stat too good] (normal)

   /tmp/ghctest-5_qx1p/test   spaces/./perf/compiler/T12234.run  T12234 [stat too good] (optasm)

(I do wish the summary omitted those long paths; makes it hard to read.)

I’m happy about the perf improvements, but why don’t they happen for other people?

T11195 is a very long-running pattern-match perf test that regularly fails on a heavily loaded machine, with a timeout. It’s very tiresome, but I don’t think it’s a regression.
