Bugzilla Automation <bugzilla at FreeBSD.org> has asked freebsd-haskell mailing
list <haskell at FreeBSD.org> for maintainer-feedback:
Bug 228727: lang/ghc cannot be used as a bootstrap compiler
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228727



--- Description ---
The package for ghc version 8.4.2 has been built with dtrace support, sadly
this results in a GHC that cannot be used to bootstrap another compiler. For
that reason 8.4.2 should be build with the `--disable-dtrace` configure flag
which was introduced as a workaround in 8.4.2. (see
https://ghc.haskell.org/trac/ghc/ticket/15040).

I currently have a patch in review that hopefully fixes this issue altogether.
