Add a $recursion_depth parameter to your sub - initialize to zero on the initial call.

Add one on each recursive call.

When the value exceeds some "reasonable" number corresponding to the max expected depth, call "Carp" and bail.

to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
