Ticket #7576 (closed bug: worksforme)
Building happy -- setup: internal error: evacuate: strange closure type 2122076
I'm running a Gentoo system and use the haskell overlay. The Gentoo-Haskell folks strongly advise using their provided packages instead of cabal-install.
When I try to emerge (=install) [dev-haskell/happy-1.18.10]( http://www.haskell.org/happy/) the build process aborts with the message
>>> Compiling source in /var/tmp/portage/dev-haskell/happy-1.18.10/work/happy-1.18.10 ... ./setup build setup: internal error: evacuate: strange closure type 2122076 (GHC version 7.6.1 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug /var/tmp/portage/dev-haskell/happy-1.18.10/temp/environment: line 878: 23486 Aborted ./setup "$@"
