GHC 7.10.2 RC: the impossible happened on hPDB-examples-1.2.0.2
When compiling with the RC for Stackage, I get:
[1 of 1] Compiling Main ( examples/Rg.hs, dist/build/Rg/Rg-tmp/Main.o )
<no location info>:
ghc: panic! (the 'impossible' happened)
(GHC version 7.10.1.20150619 for x86_64-unknown-linux):
Simplifier ticks exhausted
When trying UnfoldingDone bindIO
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: 19573
