Note one method which is not mentioned here when there is a regression in
rejecting valid code is to test the older working compiler too.
So a testing "bash" script (which returns 0 when the test should be accepted
but is not currently, and non zero otherwise) would look something like:
if old-gcc $1; then
exit 1
fi
if gcc $1; then
exit 0
fi
exit 1

And then you use that with delta or otherwise.
