Not sure how the segfault is happening, our PoW limit values are the same as LTC.

Originally the value was high, however that has being fixed.

Been running a fresh install of lubuntu in a virtual machine since the launch. Not a single segfault.

What version?

13.04 32-bit.

Ah I'm 64-bit, I wonder if that's the issue.

I haven't had a segfault since the difficulty recalc to 0.00154470, although it hasn't been all that long yet. How about you, arjay?

I got two segfaults in a row there, but it's been fine for a few minutes. Perhaps the segfault happens when the difficulty retargets?
