in reply to regex gotcha moving from 5.8.8 to 5.30.0?

I suspect it's \G and all the matching groups. Do you have some sample data and a description of what you're trying to do? There may be a way to do it without all the backrefs.

    I don't understand. There don't seem to be any backreferences in any of the regexes presented so far. Can you please clarify?

      Bad terminology. I mean the \G having to refer back to the last match.

        ... \G having to refer back to the last match.

        IIUC, the \G anchor refers to the pos of the string against which the match is being attempted (the pos from a previous, unsuccessful match attempt having been preserved by the /c modifier), and so should should be pretty cheap/quick. Is your experience otherwise?
