Did you did make clean before compiling new version? And are you sure you pasted correct log, because in that log version is: VERSION: 0.C-48240-gb9b3dc27b0-dirty?

I had today different segfault after pulling changes, that went away after I did make clean and recompiled, maybe it's something similar, so sorry if those above question may sound stupid, just trying to be helpful.

I was testing on a build from my working branch here when I thought it was on an experimental release. Unless someone else can reproduce this in master I'm going to assume it's a bug I introduced given that monster code is what I'm working on in that branch.
