Hi Paul,

Is there any particular case you are concerned about?

Dmitri

Dmitri,

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.
