Debugging stand-alone module

I've managed to get the VS2019 debugger to attach to a stand-alone WASM module, and it's stopping at break-points, but in the locals window, all variables show as "Variable is optimized away and not available". This is a debug build and I'm pretty sure all the optimizations are switched off, is there something else I'm missing?

Hi,


Did you activate the Fast Wasm Compilation mode? In "slow" mode, compiler optimizes some part of the code, which can explain your problem.

NVM found it, but setting it to fast makes no difference.

Hi,


Did you recompile your dll once you activated the "Fast Compilation" mode?


Just to be sure:

  1. Recompile your wasm in debug mode
  2. Remove generated folder which contains dll, obj, pdb...
  3. Activate "Fast Compilation"
  4. Fly


If it still doesn t work, that means there is a bigger issues with debugger


Best regards
