Hmmm. ...

Can you set a "variable watch" that triggers on a memory value that  
should not change but IS getting changed? I don't remember if Studio  
has that.

Another possibility is that you are getting a corrupted stack (ie,  
unmatched push/pops or something that writes into area used by stack)  
and you are returning to a place in ROM that is the middle of a two- 
word instruction so that everything subsequent is really messed up.  
Been there, done that!
