in reply to Mysterious crash of perldoc
perhaps you could try to run some other POD renderers on your source file, such as pod2html, pod2latex, or pod2text, etc. I think they are bundled with most or all of Perl installations. This might help you to figure out whether your POD is correct or not, or whether there is perhaps something wrong in your environment.
Or you could even try an on-line POD to HTML renderer: https://metacpan.org/pod2html.
