Good day!
I now have a crude model using a Winelib program so I can get the problem under controlled - or at least, repeatable - conditions.
Now if I knew how to set a watchpoint from inside a Winelib program, that might make it easy. If a watchpoint on an upper halfword can work. A pox on the inventor of little-endianness!
If I have to use the debugger interface I know about, I will have to refine the model a bit.
