Hi Niklas, Andreas,

I'd be happy to help. :) I know a bit about the backend (e.g., cmm level),
but it might be tricky to find there some smaller/self-contained projects
that would fit ZuriHac.
You've mentioned performance regression tests - maybe we could also work on
improving nofib?

New slow validate errors

[Ömer Sinan Ağacan]

Hi,

I see a lot of these errors in slow validate using current GHC HEAD:

ghc: panic! (the 'impossible' happened)
  (GHC version 8.5.20180407 for x86_64-unknown-linux):
Each block should be reachable from only one ProcPoint

This wasn't happening ~10 days ago. I suspect it may be D4417 but I haven't
checked.

Yes, sorry for that!

This is tracked in: https://ghc.haskell.org/trac/ghc/ticket/14989

Hi,

I'd also be happy to help. At the very least I can be around as a mentor, but
if I can find a suitable hask I may also host a hacking session.
