I warn anybody before using ARM Keil 4.13a. It generates defective code. I have spent several hours with debugging a code that has been already worked. The problem affects local variables of functions and passing arguments. Code has been wrongly compiled without any optimization. I have no courage and time to test optimizations.
I also encourage Keil not to publish Keil 4.13a any more.
Keil 4.12 seems to be OK.
Oops - I guess this happens when you are working on a Sunday @ 1AM.
On preparing my bug report to Kiel, I spotted an extra '&' that was killing my code. The funny thing is that also messed up the Locals window. Go figure.
Cheers.
It has already been pointed out that there are known issues with the Debugger...
