Simplifier ticks exhausted When trying UnfoldingDone $

[14 of 15] Compiling TieKnot          ( GameDefinition/TieKnot.hs, dist/build/LambdaHack/LambdaHack-tmp/TieKnot.dyn_o )
ghc: panic! (the 'impossible' happened)
  (GHC version 8.0.1 for x86_64-unknown-linux):
	Simplifier ticks exhausted
  When trying UnfoldingDone $
  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: 8813

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

when compiling in profiling mode the following commit (tons of INLINE and INLINABLE to ensure specialization and a couple more to debug irregularities in the output of the profiler)

https://github.com/LambdaHack/LambdaHack/commit/842070fe78f07e2fb0bce829505dcfa8465ef40f

Steps to reproduce:

1. make configure-prof
2. cabal build

when I instead do

cabal build --ghc-option=-fsimpl-tick-factor=200

it compiles, though when I touch only GameDefinition/Main.hs I always get

~/r/LambdaHack$ cabal build --ghc-option=-fsimpl-tick-factor=200
