HEADS UP: GHC 8.4.1 has issues when used as a bootstrop compiler

[raichoo]

Hi,

I've added DTrace support to GHC for FreeBSD. As it turns out this sadly
breaks the
ability to function as a bootstrap compiler. I'm currently trying to get in
a flag for 8.4.2 to
disable DTrace as a temporary workaround until I've fixed the actual issue.

I just wanted to give you a heads up to not upgrade the port to anything
higher than
8.2.x at the moment.

Kind regards,
raichoo
