Test suite triggers GHC bug on 8.0.2 #51

Closed snoyberg closed 7 years ago

snoyberg commented 7 years ago 
Preprocessing test suite 'sqls' for relational-query-0.8.3.2...
[1 of 3] Compiling Model            ( test/Model.hs, dist/build/sqls/sqls-tmp/Model.o )
[2 of 3] Compiling Lex              ( test/Lex.hs, dist/build/sqls/sqls-tmp/Lex.o )
[3 of 3] Compiling Main             ( test/sqlsEq.hs, dist/build/sqls/sqls-tmp/Main.o )
ghc: panic! (the 'impossible' happened)
  (GHC version 8.0.2 for x86_64-unknown-linux):
        Simplifier ticks exhausted
  When trying UnfoldingDone runReaderT
  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: 405365

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

I applied work around fix in https://github.com/khibino/haskell-relational-record/commit/55255c3d603428493e21cf6fd9dcbbfa229a8829 , and I uploaded fixed version https://hackage.haskell.org/package/relational-query-0.8.3.3
