FWIW on my system applying this patch only partially resolves the
org-capture issue. I'm testing with org-20160718 from GNU Elpa and
latest Emacs 25 branch from the git (Repository revision:
4157159a37b43712440da91a45a6d5f71eb96e8a).
The patch successfully eliminates the match-data-clobbered error/abort
during org-capture with all my capture templates when I have my entire
config loaded, but with a minimal recipe from emacs -Q the org-capture
match-data-clobbered error still occurs.
The minimal recipe I'm testing with is similar to that posted by Robert
Pluim on 2016-07-18, specifically
src/emacs -Q
M-: (custom-set-variables '(package-selected-packages (quote (org-20160718)))) RET
M-x package-initialize RET
C-x C-f ; find file.
C-S-backspace ; kill-whole-line.
~/.notes RET ; Open the file expected by default capture template.
M-x org-mode RET ; put the buffer into Org Mode.
M-x org-capture RET t ; Run the default "Task" capture template bound to the t key.
With your patch I still get the error:
org-capture: Capture template ‘t’: Match data clobbered by buffer modification hooks
.
It puzzles me that your patch doesn't work for the emacs -Q recipe but
does work for my normal configuration, so much so that I suspected that
I had made a mistake, but I have reset and reapplied the patch three
times and I continue to see the same results.
I hope this helps.
