RE: Core dump on AIX?

[Doug Lewan <dougl@shubertticketing.com>]

I thought I should let you know that, with the help of Glenn Morris and Erik Charlebois, I got a fix to build GNU emacs 24.3 on AIX 6.1 and it now runs very reliably.

I understand the fix is now a part of the emacs distribution.

If the majority of cooking accidents happen in the kitchen, then why don't we just cook in other rooms?

Subject: Core dump on AIX?

All,

I'm using emacs 24.1 on AIX 6.1, built here with xlc. It was configured with this line:
    ./configure --prefix=${HOME}/local --with-jpeg=no --with-png=no --with-gif=no --with-tiff=no

I get fairly frequent core dumps in emacs. They seem associated with motion but I can't say that that's absolute.

There are some observations below. Does anyone have anything to help be with this.

One failure that I /can/ reproduce reliably that suggests the above is this:
1. emacs -q file_of_interest.c &              file_of_interest.c is about 1.1MB and 34 000 lines.
2. M- 1 0 0 0 0 C-n
3. Fatal error (11)Resources lost(coredump)

BTW I can't build 24.3 as my environment stands. Making eventually produces this error:

    Emacs garbage collector has been changed to use conservative stack
    marking.  Emacs has determined that the default method it uses to do the
    marking will not work on your system.  We will need a system-dependent
    solution for your system.

(Admittedly, I'm being a bit lazy turning to the mailing list, since it does give a little hint about what to do:

    Please take a look at the function mark_stack in alloc.c, and
    try to find a way to make it work on your system.

  (And then it reveals that it's seeking help too:

      Please mail the result to <emacs-devel@gnu.org>.
   )
 )
