Devel::NYTProf is a powerful feature-rich source code profiler for Perl. (Mostly in maintenance mode, so PRs are much more likely to be acted upon than Issues.)
When running nytprofhtml, only two dot files are created: packages-callgraph.dot and subs-callgraph.dot. All other pages contain links to additional dot files, but they don't exist.
I've found an abandoned project from 2012 where the dot files existed in the nytprof/ directory. The files claim to be produced by NYTProf 4.09.
It's interesting that changing the following condition starts creating the files - but 4.09 had the same condition as the current version.
