Crash when launched -nw on Mac OS X, compiled with gcc 4.0.1

[Peter Dyballa]

Hello!

When launched in Terminal GNU Emacsen 22.0.50 and 23.0.0 both crash  
after some time. In gdb GNU Emacs continues until:

	Program received signal EXC_BAD_INSTRUCTION, Illegal instruction/ 
operand.
        0x001f26d8 in Fsqrt (arg=501192) at floatfns.c:561
        561       IN_FLOAT (d = sqrt (d), "sqrt", arg);

Last message in minibuffer is: Loading mule-util...done

Adding to the arguments -Q I get the same:

	Program received signal EXC_BAD_INSTRUCTION, Illegal instruction/ 
operand.
        0x001f26d8 in Fsqrt (arg=4216608) at floatfns.c:561
        561       IN_FLOAT (d = sqrt (d), "sqrt", arg);

and in minibuffer only: For information about the GNU Project and its  
goals, type C-h C-p.

At invocation I get:

        (gdb) run
        Starting program: .../emacs/src/emacs -Q -nw
        Reading symbols for shared libraries ..++++++ done
        No struct type named Lisp_Symbol.

The X client runs fine ...


After a few 'make distclean ; ./configure ... ; make' cycles it seems  
to be this gcc option that makes GNU Emacs crash when running with no  
windows: -mpowerpc-gpopt. This is again true for both GNU Emacsen  
22.0.50 and 23.0.0. More optimisation like -O2 works.
