Adding -DDEBUG makes an error. I had to download a file not part of emacs as suggested here:
https://lists.gnu.org/archive/html/bug-gnu-emacs/2012-04/msg01236.html

But even then, I get other errors and a failure :

Should I report either of these as a bug ?

Anyway, I changed "#if DEBUG" to "#if 0" in etags.c to avoiding loading
chkmalloc.h at all, and I can now compile but that option outputs a lot
of things to stderr (especially since my file is rather big).

But the good news is that it was so hard to get right that I ended up
looking for an actual reproducible recipe, and succeeded :

1. I have the attached files test.gro and test.el in a directory

2. I run emacs as follows from that directory :
/path/to/emacs -q -f toggle-debug-on-quit ./test.gro --eval '(message "Buffer loaded")' -l ./test.el

3. When the message "Buffer loaded" is on the screen, I hit C-g

4. I get a backtrace:

Debugger entered--Lisp error: (quit)
  looking-at("^[ 	]*:PROPERTIES:[ 	]*\n\\(?:[ 	]*:\\S-+:\\(?: .*\\)?[ 	]*\n\\)*[ 	]*:END:[ 	]*$")
  eval-buffer(#<buffer  *load*> nil "/home/youngfrog/tmp/org-mode/repro-re-match-2-internal/test.el" nil t)  ; Reading at buffer position 125
  load-with-code-conversion("/home/youngfrog/tmp/org-mode/repro-re-match-2-internal/test.el" "/home/youngfrog/tmp/org-mode/repro-re-match-2-internal/test.el" nil t)
  load("/home/youngfrog/tmp/org-mode/repro-re-match-2-internal/test.el" nil t)
  command-line-1(("-f" "toggle-debug-on-quit" "-l" "org" "./test.gro" "--eval" "(message \"Buffer loaded\")" "-l" "./test.el"))
  command-line()
  normal-top-level()

5. hit c in the backtrace window

I then get a core dump.

Please note that if, instead, I don't mention "-l ./test.el" on the
command line but use M-x load-file RET test.el RET after emacs is
loaded (and proceed) the result is not a core dump but an infloop.

Here's a debugging session of that infloop. Since it's the gdb log and
that apparently doesn't record my commands, here's what I did :
- hit C-z in gdb
- ask for a backtrace
- say "finish" until it doesn't return (happens in re_match_2_internal)
- hit C-z again
- another backtrace
- finish until I get back to re_match_2_internal
- say 'next' repeatedly until boredom

I hope this is useful.
