SIGSEGV in eix-diff from eix-0.31.5 #19

Closed moschlar closed 8 years ago

moschlar commented 8 years ago

Hi there,

I get a SIGSEGV in eix-diff recently (with optimizations disabled, too).

Here's the log from the gdb session:

I'd be happy to help test some things.

I just released eix-0.31.6 with a patch which hopefully fixes it.
