We intentionally change and improve our diagnostics between Clang revisions,
including intentionally suppressing later errors after an earlier diagnostic
for a particular issue, so I would imagine that you're going to see a lot of
false positives by this method for every real bug that you find.

If you're going to go ahead with looking for more bugs by this technique, I'd
ask that you check to see whether each change looks like a bug before reporting
it. For a parse error such as this one, if Clang changes to produce better
diagnostics (as in this case), we generally won't be interested in a bug
report. If you're not sure whether a change is a bug or not, please mention
that in the bug report so we're not left to puzzle out why you think there's a

Finally, please understand if your bug reports get marked INVALID with very
little explanation in future. I'm marking this one invalid now, because the new
