Fix buffer underrun (invalid read) triggered during diagnostic rendering. The test would overflow when computing '0 - 1'.
I don't have a good testcase for this that does not depend on system headers.
It did not trigger with preprocessed output, and I had trouble reducing the example.
Fixes <rdar://problem/13324594>.
Thanks to Michael Greiner for reporting this issue.
