zesarux: Double entries in history #21

Open maziac opened 4 years ago

maziac commented 4 years ago

Sometimes it seems as if zesarux would execute instructions twice or at least enter them into the history twice.

The same happens if calls are used instead of NOPs. I.e. there are double entries for a call.

HOW OFTEN: I checked 5x how often this occurs. After x instructions: 31712 31719 31724 31712 317124

I did the same with the NOP loop: 15417 15417 15417 15417 15417 This is more consistent.

double entries happen also without WPMEM being hit or even with WPMEM completely disabled (-14,-15):

So the main problem are the double entries itself. That the read mem breakpoint is fired seems to be a side effect.
