Extremely slow regex searches on files with very long lines

[Josef Wolf]

Regex searches on files with very long lines are extremely slow.
During the search (can take up to an hour) ^C and ^Z are not working.

Older versions (less-487 on ubuntu-18.04 and less-530 from opensuse leap-15.1) find same regex on same file within one second.

24.04 affected as well as 22.04.

Tracked down commit that caused the problem with git-bisect:

Thank you for your bug report. Any chance you could report also the issue upstream? We don't have anyone on the Ubuntu side actively working on the less sourcecode so it's not likely it will be picked and resolved from this launchpad report. Also it would help a bit if you attached a testcase example to the report

[Sebastien Bacher (seb128)]

Oh, I see now that you already reported it upstream, cross referencing now, https://github.com/gwsw/less/issues/520

Done.

But I have to admit that I had a hard time to find the correct location of the upstream repository.

Maybe the link to the upstream could be placed somewhere on the bug-reporting page on launchpad?

Problem is already fixed in newest upstream v656.

Any chance to see v656 (or at least v649) in 24.04 or 24.04.1?
