Sorry about the spam. Bugzilla keeps eating my post. Last try, this time w/o
quoting:

I'm not sure what you're surprised here. The warning from clang is *because*
the argument will always be NULL. From what little I can see, this warning is
working as intended, but of course, since you haven't posted the actual code,
much less a nice reduced test case that shows the problem, I can't really help
much.

>   Any suggestions to squelch the warning??

The warning itself told you: "note: consider using __builtin_trap() or
qualifying pointer with 'volatile'".

If you feel there is actually a bug here, please re-open with a test case and a
specific problem with Clang's behavior when compiling the test case. Currently,
I have no idea what real code led to this warning, or why you feel it was
inappropriate for Clang to warn here.
