Make perl crash

It is not easy to make perl give a segfault, but this does it. This is a known issue but apparently not easy to fix. This is completely useless except for showing people that perl is not bullet-proof.

Alternatives

There are 2 alternatives - vote for the best!

What others think

It's because of perl's liberal nature. It tries to let you get away with things you shouldn't. Read it's documentation; it states as a known bug that it doesn't enforce the warnings pragma.

Try it now, using pythonic-type scoping and you find that when you force it to only allow proper coding practices, no such failures occur:

perl -eMstrict '$x = []; push @$x, eval { $x = 1; return $x = 1; }'

Your statement is misleading. With more intellectual honesty you would have stated that 1) nothing is bullet proof, and 2) poor coding practices are especially vulnerable

What does "-eMstrict" do? With "-Mstrict -e" or "-e 'use strict; ...'" it still segfaults but with "-eMstrict" it doesn't. Google doesn't turn up anything on this option.
