Linux failures

[Thomas Miedema]

Hi,

The user001 is tracked by this bug:
> https://ghc.haskell.org/trac/ghc/ticket/1487


This is my fault. I made a patch that reenabled that test some time ago,
but it fails under certain conditions. I just proposed a proper solution to
the libraries mailinglist
<http://www.haskell.org/pipermail/libraries/2014-September/023798.html>. We
could also disable the test now, if you don't want to wait at least another
2 weeks.

With apologies,
Thomas
