My recent experience may be relevant.

I upgraded recently from 5.0.x (5.0.2?) to NetBSD 6.0.1 on my production server.

I have users that use a lot of perl, and I have to keep their
CPAN modules installed and up to date.  To keep my life simple,
I just do a cpan "upgrade", and let it run.

I tried to do this after the upgrade to 6.0.1, and it failed with this
same panic.  The package I had installed for perl was perl-5.14.2nb5 from
the 6.0_2012Q3 "batch".  After struggling with this a little, I decided to try
the perl from 6.0_2012Q4, which is perl-5.16.2nb1  When I upgraded perl
to the 5.16 package, the panics went away.

This is not necessarily a solution.  The root problem could be anywhere,
but I hope this is a useful data point.
