in thread NYTProf line report failure

Which of the output lines you provided are the result of the warn $self->filename call? Also, what does a "normal" filename look like when printed? Seeing the difference will help.

Another question is why your code is using what appears to be a module installation process? Perhaps it tries to install on-the-fly? In which case perhaps it is best to get everything installed before running the code?

    Also, what does a "normal" filename look like when printed?

    Either the it's the full path to a perl module, or one of those eval lines with parens and brackets.

    Another question is why your code is using what appears to be a module installation process?

    I'm using ExtUtils::Installed. ExtUtils::Installed::new calls ExtUtils::Installed::_make_entry which calls ExtUtils::MM_Unix::parse_version. Maybe I found another bug by analyzing Perl? (This time in NYTProf)

      I had the same question about which one were your warns. If you want to create a simple and correct output with your warning additions then just start with a simple and correct Perl script and test with it your new hypotheses. Questions without any source code are a bit rhetorical.

        Here's an SSCCE that triggers the issue when profiled by NYTProf:
        #!/usr/bin/perl use strict; use warnings; use ExtUtils::Installed; ExtUtils::Installed->new;
        Output from nytprofhtml with the added warn:
