bug#26531: Emacs crashes with adding space character

Hello,

I am running emacs 25.1 on a fully updated Fedora 25 linux.

I have stumbled upon the bug when editing the attached file and I can not figure out the issues.

In the above file, if I go to before "Usage..." and start typing anything, including whitespace, emacs crashes. Here is gdb output with bt full and backtrace.

Note that I have no command for xbacktrace.
(gdb) xbacktrace
Undefined command: "xbacktrace".  Try "help".

This has really been a major block for me. So, I was wondering if anyone can help track down the error.

Please feel free to ask questions if something is not clear.

Thanks again! 

Best wishes,
Ranjan

bug#26531: Emacs crashes with adding space character

[Paul Eggert]

I can reproduce the problem on Fedora 25 x86-64, using "LC_ALL=C /usr/bin/emacs 
-Q" (this is the bundled Emacs, Emacs 25.1), by going to the first '"' in the 
file, inserting "xxxxx" before it by typing "x" five times, and then typing 
Backspace five times. The problem is intermittent.

I cannot reproduce the problem on the same platform by running the latest Emacs 
25 built from git (this is commit bc55a5742352f14b1ff3c50d19b5d00f087bd466 dated 
2017-04-12). So I am hoping that the bug is fixed and that the fix will appear 
in the next release. If possible, it'd be nice if you tried the latest Emacs 25 too.

Was this built with ralloc.c?  The symptoms (pointers to buffer text
are garbled) sound similar to problems we had before we stopped using
ralloc.c.

Yes, it was.

Yes, indeed, this among other things does it.

I will try it with the git version. Is that the latest developmental release? 

With regard to the questions by Paul (thank you very much also!), it was not clear to me (sorry) how to include the bug report from within emacs given that the program itself had crashed. So, I just tried to follow the instructions.

Not sure if it is bug#24358.

I tried it on both the stable version released by Fedora 25 and also the version I got from the downloads part of the emacs site.

According to the unpacked tar, the last date of release was September 16, 2016.

I used ./configure and make (which is the same as make all) without any additional non-default options.

How do I figure this out? 

When I compiled it, I did not use any options in the configuration (because I wanted everything as vanilla as possible). I will look into the Fedora spec file and see if i can find this.

Thanks a bundle again to Paul and Eli for helping out!

PS: I was able to compile the git version and at least now, I could not replicate the bug on this little file using the newly-compiled emacs. This has been a very frustrating and hard to figure out for me because some files would just dump core and I could not tell what the problem was.

Well, at least, there may be a fix in the works.

Is there a date for the release of a new version? I hope that it is soon. It certainly is an important show-stopper for me, and I doubt Fedora will allow for a developmental version in their updates.

Thank you again!!

Best wishes,
Ranjan

Thanks for checking. Closing the bug report.

Not that I know of. I don't know what's holding things up. For some time I've 
thought that users are suffering significantly more by not having the new 
release than they would suffer by getting it "prematurely".

Lack of free time of the volunteer who works on that, as always.

Thanks! Is 25.2 coming out in two days? I will post on the Fedora list and also on bugzilla.

It should be out in a few days, yes.  If you post to other lists,
please don't make it too definitive, as I have no idea whether it will
be 1, 2, 3, or a couple more.  "A few days" sounds about right, and I
do hope it will be sooner rather than later.

Thanks.

Thanks! I thought that you meant two when you meant couple but it is good to know that it may be this week. 

I will see if I can get Fedora to do this for 25.1 with the ./configure REL_ALLOC=no for no (as suggested by npostavs, thanks!). 

Of course, I don't completely know what REL_ALLOC=no or ralloc.c does.

Thanks,
Ranjan

You should be able to fix this on 25.1 as well with ./configure REL_ALLOC=no

Yes, indeed, this among other things does it.

No, please try building the latest HEAD of the emacs-25 branch, or the
latest release candidate of Emacs 25.2.

If you see a file ralloc.o in the src directory after building Emacs,
then the build uses ralloc.c.

> Is there a date for the release of a new version?

Emacs 25.2 is about to be released in a couple of days, but I'm not
sure you built that version.

Eli,

The problem does not show up with Emacs 25.2.

Yes, indeed. 25.1 when built had this file after building.

NO, at that point, I did not, but the problem does not show up with 25.2-rc2 so hopefully this new release will fix it for good.

Thanks again!

Not reproducible here.

Could this be bug#24358 again?  When was your Emacs built?  (You
didn't use "M-x report-emacs-bug", so this information is absent from
your report.)
