Hi David, <br>
<br>
I'm happy to add a test case, but I don't know how to catch this
case. It's not obvious to me if any code path intentionally creates
a DeclarationNameInfo with a valid start loc and an invalid end loc.
Can you suggest a test case?<br>
<br>
Thanks,<br>
<br>
Stephen.</div><div text="#000000" bgcolor="#FFFFFF"><br>
