crash: CVS sources on Solaris 2.5.1 with gcc 3.0

[Sam Steingold]

As I already mentioned, I cannot build the current Emacs sources on
Solaris 2.5.1 with gcc 3.0 (I get a crash in malloc on startup of
bootstrap-emacs).

To make the bug report more specific, I started with a fresh sandbox
and did:

$ ./configure --with-x-toolkit=motif
...
Configured for `sparc-sun-solaris2.5.1'.
 
  Where should the build process find the source code?    
/kdd3/opt/local/src/emacs
  What operating system and machine description files should Emacs use?
        `s/sol2-5.h' and `m/sparc.h'
  What compiler should emacs be built with?               gcc -g -O2
  Should Emacs use the GNU version of malloc?             yes
  Should Emacs use a relocating allocator for buffers?    yes
  Should Emacs use mmap(2) for buffer allocation?         no
  What window system should Emacs use?                    x11
  What toolkit should Emacs use?                          MOTIF
  Where do we find X Windows header files?                /usr/openwin/include
  Where do we find X Windows libraries?                   /usr/openwin/lib
  Does Emacs use -lXaw3d?                                 no
  Does Emacs use -lXpm?                                   no
  Does Emacs use -ljpeg?                                  no
  Does Emacs use -ltiff?                                  no
  Does Emacs use -lungif?                                 no
  Does Emacs use -lpng?                                   no
  Does Emacs use X toolkit scroll bars?                   yes

here the build process goes into an infinite loop:

  make  -w bootstrap; \
fi

if I am lucky to interrupt the build process before it kills
bootstrap-emacs (actually, tweaking src/Makefile is easy :-), I get this:

$ gdb bootstrap-emacs-save -c ../lisp/core
