If I run emacs, everything's fine until I exit with M-x kill-emacs: I 
then get a SIGSEGV.

Note that the gcc that was used in gcc 3.3, using GNU as 2.13.2.1 and 
the system linker (/usr/ccs/bin/ld).
Compiling with gcc 2.95.3 works ok, as well as gcc 3.2.2 (both using 
/usr/ccs/bin/as as the assembler).

Re: Emacs segfaults in __do_global_dtors_aux on SunOS 2.7, temacsworks ok.

You need to find a Solaris wizard to fix this.

I suggest you first try the current development sources from CVS
on savannah.gnu.org.  If the bug is fixed in the current sources
then you may as well not spend any more time on it.
