The testcase also regresses on sparc-sun-solaris2.12:
The test (intentionally) does bad things that trigger the new
warning. The failures were reported last week in bug 80643 along
with a bunch of others. The latter were also fixed last week but
I overlooked these. I pruned the new diagnostics this morning
to avoid the excess failures. The test should pass again on all
targets. Thank you for your patience.
