I hear from IRC that this is from Kenner's big patch and it is very intermittent too.

I thought so.  The 32-bit hppa-linux port has a similar set of regressions
to the x86 port.

Might be fixed by:
        * gimplify.c (gimplify_compound_lval): Don't set ARRAY_REF or
        COMPONENT_REF variable fields unless they're non-constant.

And yes this was caused by your patch Kenner even if you do not want to admit it.
Please do not send email directly to me about bugs which you caused, please fix them next time
instead of complaining that you did not cause it.

The bootstrap started this morning got a little further:

stage1/xgcc -Bstage1/ -B/opt/gnu64/gcc/gcc-3.5.0/hppa64-hp-hpux11.11/bin/ -c   -
g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototyp
es -Werror -fno-common   -DHAVE_CONFIG_H    -I. -Ijava -I../../gcc/gcc -I../../g
cc/gcc/java -I../../gcc/gcc/../include -I../../gcc/gcc/../libcpp/include -I../..
/gcc/gcc/../libbanshee/libcompat -I../../gcc/gcc/../libbanshee -I../../gcc/gcc/.
./libbanshee/points-to  ../../gcc/gcc/java/class.c -o java/class.o
../../gcc/gcc/java/class.c: In function `ident_subst':
../../gcc/gcc/java/class.c:274: internal compiler error: in emit_group_load, at
expr.c:1879

So, this one may be fixed.  Regarding the timing of the failure, it was
possible to bootstrap sucessfully after the following patch was installed:

2004-06-21  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>

	R rtl-optimization/14782
	* pa.c (emit_move_sequence): Use SFmode for 4-byte modes when doing
	...

Should I open a new PR?

Dave

If you're still seeing a problem, yes, open a new PR.
