Thanks all for the excellent responses. To answer the various suggestions and questions:

Yes, I posted the exact script that I'm running. Perl version 5.22.1, Ubuntu 16.04.

Trying huck's or ikagami's suggestions didn't change things, unfortunately.

Running on the same line repeatedly shows no memory growth, which I can't explain. It's thus possible it's only certain lines of the input file that cause the problem but I'm struggling to see how to identify which.

Thus it's difficult for me to post data on which I see the problem. The file I'm reading in is the Wikidata data dump (33GB bzipped) https://dumps.wikimedia.org/wikidatawiki/20180201/wikidatawiki-20180201-pages-articles.xml.bz2 (I usually read it in with IO::Uncompress::Bunzip2 but verified that the issue still occurs when unzipped by taking the first 2GB of that file unzipped)

I'll work on trying to get Data::Diver working and identify problematic lines of the input file.

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.
