Comment (by mfox):

 I did a perf build from today's master, and I'm seeing a ton of test
 failures. Like hundreds. Most are "bad stderr" or "stderr mismatch". I
 notice a lot of tests complaining about "unable to decommit memory:
 Function not implemented". This may be the cause of all the failures. Any
 idea what it's about?

 Building from e2b66a0ef0a0d8ff5cdb681edd8309954ef0a08a

 I made sure to update all of my submodules with

     git submodule update --init

 as recommended in
 https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources to avoid
 the old iserv problem mentioned above.

 Any ideas? Should I open a new bug?
