Description

What's the problem? Describe what went wrong.

When starting any games with the DSP LLE recompiler audio engine dolphin-emu will print 'WriteRest: op out of range (0x44555039 uses 0x7fecbc112af8)' and then segfault. Both HLE emulation and the LLE interpreter seem to work normally.

What steps will reproduce the problem?

  1. Set the DSP Emulator Engine to the DSP LLE recompiler.
  2. Start any game.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?
