From: Nicolas Richard <theonewiththeevillook <at> yahoo.fr> To: bug-gnu-emacs <at> gnu.org Subject: 25.0.50; SIGABRT in re_match_2_internal Date: Tue, 24 Mar 2015 16:14:22 +0100
Hello,
I can't reproduce from -Q, but I can reproduce with my init file. I'll
be glad to issue commands in gdb as needed but making a reproducible
recipe from -Q would take more time.
The bug is triggered by (looking-at org-property-drawer-re) with point
at the beginning of a relatively big (35 lines) drawer in some specific
file of mine. It takes a long time. While it runs, I hit C-g (with
debug-on-error on) to bring up the debugger. Then hitting 'c' in the
debugger makes emacs unresponsive : gdb took control because of a
SIGABRT.
Here's the value of the regexp :
org-property-drawer-re is a variable defined in `org.el'.
Its value is
"^[ ]*:PROPERTIES:[ ]*\n\\(?:[ ]*:\\S-+:\\(?: .*\\)?[ ]*\n\\)*[ ]*:END:[ ]*$"
Here's the bt :
Program received signal SIGABRT, Aborted.

It would help if we could reproduce it.
What happens if you copy the buffer in question ("* Guidance
2013-2014\n:PROPERTIES:\n:ATTACH_DIR_INHERIT: t\n...") to a temporary
file FOO, edit it with "emacs -Q FOO", and then run M-x (looking-at "^[
\t]*:PROPERTIES:[ \t]*\n\\(?:[ \t]*:\\S-+:\\(?: .*\\)?[ \t]*\n\\)*[
\t]*:END:[ \t]*$") RET ?

It runs fast and I can't trigger the bug.

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 :
> In file included from etags.c:180:0:

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.

Thanks. I reproduced that problem. It's an issue with the Emacs debugger, not with regular-expression matching. (The regular expression matcher is very slow with your example -- which is a problem, but I suggest filing a separate bug report for the performance problem, as this bug report is about a SIGABRT.) I fixed the problem in master by applying the second and third attached patches (which fix some related bugs while I was at it) and am marking this as done. At least, it works for me; if it still doesn't work for you we can reopen the bug report.
