GHC 8 crash when building "chatter" library

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

changed weight to 5

added Tbug Trac import labels

Attached file stack.yaml (download).

Modified file from master branch

With -fsimpl-tick-factor=200 it worked just fine. I don't know if it should be considered bug?

Attached file InstanceSerialize.hs ($1208).

Thanks for reporting.

Can you try upgrading cereal to version 0.5.2? I think that fixes it.

It is working fine with 0.5.2 without need of that option.

It works for me as well, using GHC 8.0.1 and http://www.stackage.org/snapshot/nightly-2016-06-02, which contains cereal 0.5.2.0.

This seems to have fixed it, from the cereal 0.5.2.0 release notes:

Split the GSerialize class in two, to deal with a GHC bug (thanks Austin Seipp!)

The GHC bug they refer to is #5642, and it is still open.

Thanks again for reporting.
