I have installed a patch to fix the bootstrap failure resulting from
Jan's patch.  I now see the following assembler warning:

stage1/xgcc -Bstage1/ -B/opt/gnu64/hppa64-hp-hpux11.00/bin/ -c   -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include \
	   ../../gcc/gcc/c-opts.c -o c-opts.o 
/var/tmp//ccAEh2VX.s: Assembler messages:
/var/tmp//ccAEh2VX.s:592: Warning: .space repeat count is zero, ignored
/var/tmp//ccAEh2VX.s:598: Warning: .space repeat count is zero, ignored
...

I believe that this has been reported on other ports as well.

I misunderstood your comment.  The "-O1" optimization comment was with
respect to the testsuite failure and not the current bootstrap problems.
