Any one have any others?

I just fixed a whole bunch of sort-related ones, which is what got me thinking about this. If your perl is less more than a week old, these should kill it:

  perl -e'sub f{undef &f} ()=sort f 1,2'
  perl -e'sub f{goto sub{1}} ()=sort f 1,2'
  perl -e'@a=(1..10);@a=sort{@a=(1);0}@a'

perl -e'@a=(1..10);@a=sort{@a=(1);0}@a'

That works fine for me on 5.8.0 buts segfaults on 5.8.7.

Since 5.8.4, @foo = sort @foo is optimised to be an in-place sort of @foo, which is what makes it die so messily.
