What's the problem? Describe what went wrong.

While testing #9584 (must be done with 5.0-540 or later), attached BexCFcrash.png will appear consistently when trying to use a cloned Captain Falcon moveset final smash. These messages have consistent PCs (at 0x8089a6c8) across multiple sessions of Dolphin 5.0-5667.

If I set a breakpoint at 0x8089a6c4 or 0x8089a6c8 and then step through the code until I hit the panic alerts, the same invalid reads will occur when the PC is at a different value (0x8089a6f8). See attached PC8089a6c8.png. These messages have consistent PCs across multiple sessions of Dolphin 5.0-5667.

Dolphin 5.0-540 will produce panic messages at 0x8089a6c0 with no breakpoints and 0x8089a6f8 with breakpoints set.

Since the emulated PC remains consistent across testing cases but varies depending upon breakpoint usage and build version, something is probably wrong here.

What steps will reproduce the problem?

  1. Reproduce #9584 on Dolphin 5.0-540 or later.

Alternatively, you could try this with any panic handler message that should give consistent PC readouts.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

5.0-5667

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
