core dump in bootstrap-emacs

[Giorgos Keramidas]

Hi all,

I've been having 'make bootstrap' problems with versions of CVS
recently.

The last version I can successfully bootstrap is:

  changeset:   80041:df347cacb5a9
  user:        gm
  date:        Mon Mar 19 20:59:53 2007 +0000
  summary:     Change form of license text to match rest of Emacs.

I haven't been able to track down which particular change is the
one for which the problem started happening, but several versions
from HEAD, including the latest one I have pulled out of CVS and
into my Mercurial workspace:

  changeset:   80096:22cf3bca1ad2
  tag:         tip
  user:        gm
  date:        Wed Mar 21 07:13:06 2007 +0000
  summary:     *** empty log message ***

throw a core dump about half-way through the build, when
gnus-delay.el is compiled:

Repeated builds of the same source tree *always* throw a core
dump when gnus-delay.el is compiled, but there are no changes to
lisp/gnus/ between the last version I can successfully bootstrap
and this one.

A backtrace of bootstrap-emacs when this happens is attached
below.  I still have the build tree and the core dump around, and
I can keep it as long as necessary.

Any ideas how to proceed in tracking down why bootstrap-emacs
dumps core here?
