This is the worrisome line.

First, could you confirm if you did the full complete portage steps
while migrating:

- tweak USE, profile etc etc
- emerge -avUND world
- emerge -av @preserved-rebuild
- emerge --depclean
- revdep-rebuild [seldom necessary these days, I usually do it out of
habit...]

Let's first establish if portage reckons the system is consistent before
trying to track down why your session segfaults
