Comment (by Henk-Jan):

 I got almost the same message when compiling package SFML:

 ~~~~
 [34 of 72] Compiling SFML.Graphics.Transform ( dist\dist-sandbox-
 12e87adf\build\SFML\Graphics\Transform.hs, dist\dist-sandbox-
 12e87adf\build\SFML\Graphics\Transform.o )
 ghc.exe: panic! (the 'impossible' happened)
   (GHC version 7.10.1 for i386-unknown-mingw32):
         Simplifier ticks exhausted
   When trying UnfoldingDone $j_s8N2
   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: 380264
 ~~~~

 Setting -fsimpl-tick-factor=20000000 did not help. I am using GHC 7.10.1
 on Windows.
