Have you used strict and warnings?

At a first look I see two potentially fatal problems here:

The use of local @current instead of my @current could work fine, but should be avoided and I'm not sure what can it do in a (deeply) recursive function.

The same applies to $temp and @mainarray, but this is not fatal as the first is not reused after recursion and the latter is intended to be a global. But it is anyway bad practice.

Bottom line: strict&warnings are your friends, (almost) always.

$i is not declared lexical (my) but is a global, so every recursion corrupts the value of $i of the previous and pending executions

Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."
