( #3333=superdoc: print w/replies, xml ) Need Help??

Hello, thanks for the suggestions!

I think I should have been specific -- when I said "not sparse", I actually meant that the data structure had been fully created in advance with a loop exactly like this. I've added in the checks, and before the program the program crashes (about 3 hours of CPU) it does not every autovivify.

One thing that goes on inside the #do great deeds is to change values in the Array part of the HoHoA, and I had expected that to be the cause of my memory leak. I'm really confuzzled as to why this:

foreach my $value ( @$subarray ) {

would eat up memory. I would have guessed it would use one scalar's worth (perhaps 15 bytes of data), and that this memory would get reused over & over again. Instead, the script runs on this loop for a few hours before using up all the memory.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
