Also in `cabal install diagrams`:
{{{
[2 of 5] Compiling Graphics.Svg.Core ( src/Graphics/Svg/Core.hs,
dist/build/Graphics/Svg/Core.o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.8.4 for x86_64-unknown-linux):
Simplifier ticks exhausted
When trying UnfoldingDone
base:Foreign.Storable.$fStorableWord8_$cpokeByteOff{v r2gn} [gid]
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: 34200
}}}
(On Ubuntu server 15.10).
Output from `-ddump-simpl-stats` is attached as `diagrams-dump-simpl-
stats.txt`.
