Yes. For example, I call (defun yant/vc-git-current-branch () "Get current GIT branch." (and vc-mode (cadr (s-match "Git.\\([^ ]+\\)" vc-mode)))) with s-match wrapping its code into save-match-data. > Calling xbacktrace will show a Lisp backtrace, which could be > educational here. (gdb) xbacktrace Undefined command: "xbacktrace". Try "help". I am not sure what you mean by xbacktrace. Also, as Stefan pointed, number of markers may or may not be a problem here. However, I had a similar issue even with Emacs 28 when we tested creating a huge number of markers in buffer + re-search-forward. I ended up seeing similar perf logs that time. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at . Support Org development at , or support my work at
