Says samtregar:
Um, cool! But it leaks memory at an insane rate on 5.6.1.
Jeff Pinyan explained this one to me. The code in the regex captures the first instance of @ss, and keeps appending to it, 1023 new elements every time through the loop. You can fix the problem by using a static variable: 
{ my @ss;
  sub substrings {
    @ss = ();
    $_[0] =~ /.*?(.+?)(?{push @ss, $1})(?!)/;
    @ss;
  }
}
