Comment(by simonmar):
I managed to get a segfault with this example and an up to date GHC built
yesterday, using the suggested options (`-s 400 +RTS -N4`). I've rebuilt
the binary with `-debug` and I'm trying to provoke a segfault again, but
two runs so far have been sucessful:
{{{
Generating a random graph of size 400.
Graph contains 400 nodes and 59999 edges.
Dijkstra search time for shortest paths: 993.855562s
Etage search time for shortest paths: 0.172937s (5.0s timeout)
Etage graph (external structure) growing time: 7.674317s
Found 0.75 % shortest paths.
etage-graph-test: DissolvingException "()"
[1] 31310 exit 1
}}}
at least, I assume that's a successful run.
I'm not hopeful about finding this bug, because the program takes so long
to run and ties up 4 cores. I'll keep trying though.
