 We're trying to use NixOS to automatically run our acceptance tests in a
 VM on commit, in order to guarantee system stability. However, we're
 periodically seeing our web server component, compiled with GHC 7.8.2 is
 failing to start up. When it fails, the error message is always:

 {{{
 internal error: evacuate(static): strange closure type 0
 (GHC version 7.8.2 for x86_64_unknown_linux)
 Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
 }}}

 Happy to do more debugging on this, but I'll need to be pointed in the
 right direction.
