persistent bootstrap failure: Memory exhausted--use C-x s ...

[Jim Meyering]

Hello,

I normally bootstrap the latest emacs (updating sources from git daily),
but for the last ~9 days it's been failing on x86_64 Fedora 13:

  ...
  No MH variant found on the system
  Wrote /home/j/w/co/emacs/lisp/mh-e/mh-xface.elc
  Compiling /home/j/w/co/emacs/lisp/language/hanja-util.el

  In toplevel form:
  ../../../../home/j/w/co/emacs/lisp/language/hanja-util.el:6437:6:Error: 
Memory exhausted--use C-x s then exit and restart Emacs
  make[2]: *** [language/hanja-util.elc] Error 1
  make[2]: Leaving directory `/t/jt-FqYKau/emacs/lisp'
  make[1]: *** [compile-main] Error 2
  make[1]: Leaving directory `/t/jt-FqYKau/emacs/lisp'
  make: *** [lisp] Error 2

I can't be the only one configuring to an empty (new prefix)
and running "make bootstrap", so I suppose it's something
in my set-up.  Maybe no one else is doing that with F13...

Both srcdir and non-srcdir builds fail,
with and without this PATH-limiting export:

  export PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/bin/X11
  ./configure --prefix=$prefix && make bootstrap

Any suggestions?
