Could you explicitly mention the date of your last successful bootstrap when
reporting bootstrap failures on mainline?  [I see that the bootstrap compiler is
gcc version 3.5.0 20040621 (experimental), is that the right date?]

Confirmed with gcc version 3.5.0 20040714 (experimental) and BOOT_CFLAGS=-O. 
The regular bootstrap (i.e. without setting BOOT_CFLAGS) is not affected.

Note that you should not set CFLAGS when bootstrapping the compiler, because it
may trigger bugs in the bootstrap compiler, which we don't want to mix with bugs
in the bootstrapped compiler.

I understand. But somebody better fix the instructions on the web site, which
show not only that but -fno-implicit-templates, the subject of another recent
bug report.

http://gcc.gnu.org/install/build.html

If you want to save additional space during the bootstrap and in the final
installation as well, you can build the compiler binaries without debugging
information as in the following example. This will save roughly 40% of disk
space both for the bootstrap and the final installation. (Libraries will still
contain debugging information.)

          make CFLAGS='-O' LIBCFLAGS='-g -O2' \
            LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap

It does talk about "non-standard CFLAGS" a few paragraphs below this, but only
in referring to libiberty. It's unclear what is meant by "non-standard".

What is needed is an actual example of a recommended command line.

------- Additional Comments From ebotcazou at gcc dot gnu dot org  2004-07-14 22:09 -------
The stage2 compiler (and more precisely reload.c:combine_reloads) is miscompiled
by the stage1 compiler.  The bug stems from a bad interaction between libcalls,
CSE and loop invariant motion that would probably not be easy to fix.

However, I don't want to fix it because it uncovered what appears to be a major
problem in:

2004-07-09  David S. Miller  <davem@nuts.davemloft.net>

	* config/sparc/sparc.h (processor_costs): Define.
	(sparc_costs): Declare.
	* config/sparc/sparc.c (cypress_costs, supersparc_costs,
	hypersparc_costs, sparclet_costs, ultrasparc_costs,
	ultrasparc3_costs): New.
	(sparc_override_options): Set sparc_costs as appropriate.
	(sparc_rtx_costs): Use sparc_costs instead of messy
	conditionals.


The bootstrap failure should go away after this problem is corrected.

Indeed. I'll try to have them changed.
