macOS (Apple Silicon) + CrossOver (Wine/Rosetta): generalized crash when any detour runs — “rosetta error: no code fragment associated with the given arm pc”

[fdotcico]

Describe the bug

On macOS (Apple Silicon) running WoW via CrossOver (Wine) with a Rosetta x86 shim, nampower.dll loads but the game terminates as soon as a detoured function runs.

The crash message is:

rosetta error: no code fragment associated with the given arm pc

Environment

• Machine: Apple Silicon (M3 Max)
• OS: macOS (Apple Silicon)
• Runtime: CrossOver for macOS (Wine) + Rosetta x86 shim (rosettax87)
• Graphics stack at runtime:
  MoltenVK 1.2.10 (Vulkan 1.2.290)
  DXVK v1.10.3-20250511-async (macOS)

To Reproduce

• Download nampower.dll (32-bit, x86)
• Place nampower.dll alongside WoW root folder and add it to the txt DLL file
• (Option 1) Use TurtleSilicon app
• (Option 2) Launch via CrossOver/wineloader using the Rosetta shim (command similar to):

WINEDLLOVERRIDES="d3d9=n,b" MTL_HUD_ENABLED=0 MVK_CONFIG_SYNCHRONOUS_QUEUE_SUBMITS=1 DXVK_ASYNC=1 \
  /path/to/rosettax87 /path/to/wineloader2 /path/to/WoW.exe

Logs (trimmed)

rosetta error: no code fragment associated with the given arm pc

Thanks a lot for any guidance! 🙏
