Sorry all, I tried to respond directly to Bob, but can't seem to mail to
his given address, so quit reading now if you're not interested.


Bob, 

> Does anyone know if TI reads this conference?

Yes, we do.  We just don't contribute on a regular basis.  

> Does TI have an Internet address so I could send this to them?

Yes. (see return address) 

> Anyone else have any thoughts on this?

Thanks for the report.  By the way, we do have a hotline
which operates during business hours (713-274-2320).  It is 
staffed with engineers who are knowledgable about current compiler 
bugs, and are responsible for logging and routing new bug reports 
to us (the development group).  This is the best and most reliable 
method of reporting bugs.   You could send me mail, but I may never 
actually get around to handling it in a formal matter (read: it may 
not ever get fixed). 

Finally, about your bug.  It had to do with using the constant
0x80000000 in any additive expression. In your example, 
(0x7FFFFFFF + 1) was constant folded to 0x80000000.  It shouldn't
have anything to do with the declaration of variables used in the
same expression (as you suggested in your message). 
Fortunately, this shouldn't (doesn't) happen too often, but
still doesn't excuse a stupid bug.  At any rate, it will be
fixed in the next release (due out "soon").
