Weird Error when compiled Proc code with +Ofast compiler option

Typically customers don't do it. If anything, they patch up to the latest version. Or they contact the Response Center and let HP do it.

If you would like to binary search for the bad function, you can use "+opts filename" and inside filename, you can add:
+O1=func1 +O1=func2

Then change it to +O2= to see when it fails.
