I’m seeing this quite a bit in a project at work
heffalump: internal error: evacuate: strange closure type 28723585
(GHC version 9.0.2 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
I did some searching but found discouragingly little information. Maybe someone here know more and can offer some insights?
