Installation problem of Emacs 21.3 with GCC 3.3 /Sparc Solaris 8.

Installation problem of Emacs 21.3 with GCC 3.3 /Sparc Solaris 8.

[ishikawa]

I have an installation problem of Emacs 21.3
using GCC 3.3 under UltraSparc Solaris 8.

I suspect a bug of GCC 3.3 (and opened a bug report at bugzilla of
gcc.gnu.org, bug 11386), 
but wonder if others have experienced similar problems using
the recent GCC versions.

However, GCC 3.2.3 works fine and I could install
Emacs using 3.2.3.
But I have other reasons to prefer using GCC 3.3 on the said machine, and
so would like to resolve the issue one way or the other if possible.

Below is a quote from somewhat edited bug report that
I posted to bugzilla at gcc.gnu.org.

Since emacs is a huge program, even if it is GCC 3.3 that 
miscompiles the code, it is hard to isolate the problem
into a small section of C source code in Emacs.

I would appreciate to hear similar experiences under various
platforms (this would help GCC folks to dig deeper into the problem or
narrow the search area)
and workaround. 
And if someone knows the exact cause (a bug in GCC 3.3 maybe?),
that would be great. 
(Is it possible that unexec.c or its friend need modification for GCC
3.3, or configure is not picking up the proper unexec*.c for 
GCC 3.3 and solaris 8 combination? Wild guess at best.)

This is still insufficient information, but I am posting
the gdb log to solicit more input from Emacs user community who
may have experienced similar problems using the latest GCC 3.3 under
sparc solaris and other platforms.

Basically, after a binary compile of the emacs program,
the emacs installer tries to compile
so called emacs lisp programs into its own internal byte code.
During the byte compiling, emacs aborts.

The final gdb output is as follows:  (details below.)

|Program received signal SIGSEGV, Segmentation fault.
|0x41e90 in __do_global_dtors_aux ()
|(gdb) #0  0x41e90 in __do_global_dtors_aux ()
|#1  0x18931c in _fini ()
|#2  0xfee9bca4 in _exithandle () from /usr/lib/libc.so.1
|#3  0xfef1f87c in exit () from /usr/lib/libc.so.1
|#4  0xd2b20 in Fkill_emacs (arg=0) at emacs.c:1830
|#5  0x137d20 in Ffuncall (nargs=1, args=0xffbee31c) at eval.c:2659

This suggests that a part of emacs gets miscompiled by
by GCC 3.3 under ultra sparc solaris 8.
Emacs seems to have detected something funny and tries to quit calling
Fkill_emacs function, but
by that time, something (memory[code/stack] area?)
 was either broken from the beginning
or corrupted during the run, and during the exit processing
the program seems to have encountered a fatal segmentation error.

Using GCC 3.2.3 under the same OS, the byte compilation
succeeds and the installation succeeds.
The resulting Emacs is usable as far as I can tell.

Atttached is the problematic run, under gdb, of the Emacs binary that
gets compiled using gcc 3.3.

I run a particular byte compilation that triggered the abort by using
a shell script break.sh.  It runs the EMACS binary under gdb.
