--------------------------------------+---------------------------------
While I try to build "chatter" library from GitHub with Stack with GHC 8.0
resolver I got that crash:
[ 9 of 23] Compiling NLP.Corpora.Brown ( src\NLP\Corpora\Brown.hs, .stack-
work\dist\b7fec021\build\NLP\Corpora\Brown.o )
ghc.exe: panic! (the 'impossible' happened)
(GHC version 8.0.1 for x86_64-unknown-mingw32):
Simplifier ticks exhausted
When trying RuleFired Class op unsafeShiftR
To increase the limit, use -fsimpl-tick-factor=N (default 100)
If you need to do this, let GHC HQ know, and what factor you needed
To see detailed counts use -ddump-simpl-stats
Total ticks: 11403800
