Bugzilla Bug 111183

When trying to emerge ghc-6.4.1-r1, I am getting the error:

[...]
edison/Seq/ListSeq.hs:32:33:
    Warning: Deprecated use of `Sequence.concatMap'
             (imported from Sequence):
             This module is unmaintained, and will disappear soon

I hope that this is fixed for now. The fix is a workaround only, so
please re-open if the problem persists.

I think I've hit the same problem with 6.4.2 and error messages:
GCCompact.c:902: warning: dereferencing type-punned pointer will break
strict-aliasing rules
GCCompact.c:905: warning: dereferencing type-punned pointer tee: standard
output: Resource temporarily unavailable
tee: write error

In principle, this is an upstream bug:

http://hackage.haskell.org/trac/ghc/ticket/724

GHC is likely to crash with this error whenever it is called in a context
where tee is used. The only reliable way around this is not to use tee
anywhere,
which for portage usually can be prevented by disabling any form of logging
while emerging ghc.

Looks like this one will get fixed in ghc-6.8. I'd be a bit nervous about
backporting the changes to 6.6.
