Regardless of the problem itself, it worries me that the compiler is trying to optimize my assembly code. I certainly understand more about my assembly code context than the compiler, so any attempt by the compiler to "improve" it will most likely break something.
Even if it's necessary for the compiler to analyze small assembly snippets in the middle of a BASIC routine (in order to figure out how to integrate Assembly code with surrounding BASIC code)... perhaps compiler optimization could be disabled whenever a routine is written 100% in Assembly? Or perhaps ZX BASIC could provide a directive (or command-line option) to disable attempts to optimize Assembly code implemented by the programmer, and only optimize Assembly code produced by the compiler?
