No, I don't have specific usage cases that concern me.
As I said a minute or two ago in a reply to Ralph, my concern is that the
Sandia codes provide an "existence proof" that "really smart people" can
write questionable code at times. So, I fear that a larger-than-expected
fraction of real codes would generate warnings.
