scan-results.html

Please find attaches a Coverity Scan report of highlight 3.42. It contains some valid issues, including the one about DEADCODE, which is, from my point of view, a copy&paste error, because the line
   3459|   	if (nextText == string::npos)
should rather read:
   3459|   	if (nextText2 == string::npos)
because of:
   3458|   	size_t nextText2 = line.find_first_not_of(" \t", nextText + 1);

Another would be the MISSING_BREAK issue, which you can mute with a comment like this:
   /* Falls through */

These are only two examples, but there are surely more valid issues.

I can try to help with it, if you wish, but I'm afraid I cannot test the changes properly, thus I created this bug report.

Hi Milan, highlight 3.44 is available at this moment. Can you please run this test against 3.44 and report this bug upstream? Thanks.

Comment 2 Milan Crha 2018-09-20 11:42:50 UTC 
I'm not sure what the upstream is. `rpm -qi highlight` says:
   Bug URL     : https://bugz.fedoraproject.org/highlight
which basically lists bugs filled here.

I'll re-run the test with newer version, I should do it immediately, I'm sorry I didn't.

Ah, thanks for upstreaming this. Feel free to close this and get any fixes once they are officially released.

My offer to help with the fix still applies, just let me know if you'd like me to provide any patch (I want to avoid work duplication, in case anybody else would like to work on this).
