No.  The reported locations remain unaffected (errors/warnings at test.cc:12:5
and test.cc:12:7, notes at test.cc:9:34).  Just that (after replacing "ignored"
with "warning") they get reported as errors with -O1 and r232893 included, and
as warnings otherwise (i.e., either with -O0 and r232893 included, or with
either -O0/1 and r232893 reverted).
