in thread Perl is dying

Interestingly, when I looked at the optree above you'll notice that the custom sort sub { $a->[0] cmp $b->[0] } got entirely elided. Perhaps someone snuck in an interesting sort of optimization to the sort function where even more complicated things like that are actually performed in native C and not actually done in perl at all.
