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.

    "My two cents aren't worth a dime.";
      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.
