Yes, I did a regression search. See
http://gcc.gnu.org/ml/gcc-testresults/2007-03/msg00674.html
for r122820 linux results. I did a full bootstrap of C with r122820 on
hppa2.0w-hp-hpux11.11. Didn't run testsuite.
The same error occurs on both hpux and linux.
Removal of the middle hunk of Richard's change does not fix the problem.
I had thought the issue might be related to negative ashifts.
