For whatever its worth, I started seen random segfaults starting between
5.18 and 5.20 somewhere.  I actually have a bizarre way to reproduce the
one I see reliably by moving a return in my code.  I'm not sure if mine
is related to the segfault you are seeing, but you might try downgrading
to 5.18 if that is an option and see if the problem goes away.

I'm stuck on 5.16 until I can figure this out because regexes have nasty
bugs in 5.18 (see

I am planning to bisect against perl 5.19 git to figure out where this
broke, but I just haven't had time yet.
