Sorry, the problem isn't fixed, although we now have "-mdisable-indexing"
in the compilation commands for ada:

stage1/xgcc -Bstage1/ -B/opt/gnu/hppa2.0w-hp-hpux11.00/bin/ -c -g -O2 -mdisable-
indexing     -gnatpg -gnata -g -O1 -fno-inline \
 -I- -I. -Iada -I../../gcc/gcc/ada ../../gcc/gcc/ada/a-except.adb -o ada/a-excep
 t.o

 +==========================================================================+

The analysis in the original report showed that the segmentation fault
was due to a misaligned displacement for a load.  It didn't use an insn
affected by the "-mdisable-indexing" option.

Thanks for fixing the Makefile problem.  I'll reopen the PR.
