Steps to reproduce:

stack install graphmod
git clone
cd cardano-sl
find  -name '*.hs' | xargs graphmod -q >
dot -Tpdf -o modules.pdf 2>modules.err

Observe segfault. modules.err will contain this.

$ dot -V
dot - graphviz version 2.38.0 (20140413.2041)

This is most likely a bug in graphviz, but I'm creating a bug report here to let you know of this issue. The graphviz issue is here.

Yeah, I've encountered this also. It seems like it's been a long standing bug in graphviz. It doesn't seem to happen with version 2.40.1, which you can get by downloading the source code from the graphviz web-site and building it.
