I seen similar issues when I first started building the master branch, 
seg fault in about the same spot.    My issue was related to having 
multiple versions of libraries installed and I was picking up the wrong 
libraries.  Do you still have the old libraries installed anywhere?

I did a build a on the 21st with a pull from master and its working fine 
for me. You might try adding "--loglevel debug"  to see if it gives you 
additional information.
