Thanks again for the report.
I'm hopping over to Ubuntu 13.10 and will have a look at this. It would
definitely be helpful to know a few things (which I'm going to have to
guess about here):
* What compiler are you using? gcc or clang?
* What flags did you pass to the compiler when you compiled? Was it a debug
build? Was it optimized?
I'll file a bug if I'm able to cause a seg fault. Yesterday I had a
check-in that fixed a seg fault under Linux - not sure if that's something
you were hitting.
I'll post what I see.
