Emacs segfaulting on FreeBSD 9.1-RELEASE (amd64) during memory allocation.

Hi,

I tried bzr revision r113270 on my FreeBSD 9.1-RELEASE (amd64), and it
segfaulted during bootstrap process, (the compilation of files in "lisp"
directory). It generated a core-file lisp/bootstrap-emacs.core which has more
than 3-million (that's when I lost patience) recurring stack frames like
following:

Following is the configure line I used:

./configure --localstatedir=/var --with-x-toolkit=gtk3 --with-xft --with-m17n-flt --with-libotf --with-imagemagick --with-gsettings --with-gconf --with-xim --with-sound --with-dbus --with-xml2 --with-gnutls --with-acl --with-file-notification=gfile --x-libraries=/usr/local/lib --x-includes=/usr/local/include --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ --build=amd64-portbld-freebsd9.1

Please let me know if you need more information from the core file.

Thanks

I think this is fallout from Bug#14569, and
I'll reply there.

It didn't fix for me. And this time I ran compilation with "memoryuse" limit set
to 128M and "vmemorysize" limit set to 512M, and back trace is not so helpful:

Thanks Paul!

The emacs-24 branch builds correctly on FreeBSD 10.0-CURRENT here.  So I
just pulled your commit from the trunk ofr the Git repository and tried
a local build again from this revision:

  $ git ll -1
  5da8d1b - (HEAD, origin/trunk, trunk) Try again to fix FreeBSD bug re multithreaded memory alloc. (3 hours ago) <Paul Eggert>

with the following options:

    ./configure --prefix=/opt/gnu --without-x

This compiled Emacs successfully on FreeBSD, and resulted in the
following output from configure:

   Configured for `amd64-unknown-freebsd10.0'.
