I *think* I am not mixing them. I'm running builds either in ghc-build (lndired to ghc-working,
this often gets blown away) and ghc-validate (these are in-tree builds, cleaned with
maintainer-clean). There are no builds in ghc-working.

Thanks for the tip, I'll try that.
I'll also try to debug my problem if I find some time. I think this deserves a bug report.
