I was pretty sure the test was correct and that your patch was wrong
and just papering over a bug elsewhere -- I'd hit the same problem in
the PA64 port when I dropped it into the official GCC sources and
tried to bootstrap it.

I am grateful that you reduced the testcase to something manageable and
checked it into the testsuite.
