Prime Time for an Obfuscation

With all the prime number fun going on over here, now seems a good chance to dust off and present an obfuscation that just needed a little polishing up.

Given a positive integer argument, this program will display all of its prime factors.

$;=pop;{$.= 0;map{$;%$_ or$.||=$_}2 ..sqrt$;;;+ $.||die$;-j .$/;warn$.. $/;$;/=$.;n until+redo}

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/

Replies are listed 'Best First'.

    Did someone have trouble running it against this number: 1234567890123111? 5.8.8 on MSWin32

      It tries to create a list containing 2..sqrt(1234567890123111). So it starts to allocate 33.5M entries, taking a long time to spin as much RAM into place as it can, before it (I presume) dies (having caused way too much other stuff to swap out). Is that what you mean by "problem"? :)
