Wildcards like "__py*" should work (with "*"). But the "*" can only be at the end currently, I believe. -s ASYNCIFY_WHITELIST='["__pyx_pf_5renpy_2gl_6gldraw_6GLDraw_"...' > warning: Asyncify whitelist contained a non-existing function name: > __pyx_pf_5renpy_2gl_6gldraw_6GLDraw_ ($__pyx_pf_5renpy_2gl_6gldraw_6GLDraw_) > > Also llvm-nm doesn't seem to support listing WASM. > Correct, llvm-nm is only aware of LLVM IR. Wasm object files contain wasm. To see the names in them, build with something like -g or --profiling (so names are kept) and use binaryen's wasm-dis. You can also inspect the binary directly.

If it in the binaryen API, it could be the asyncify stack is too small. But here it looks like it's in a user function - it could be that an import was called that started a sleep, but asyncify was not aware of it, and control flow ends up in the wrong place. Adding some debug logging in your sleep function, and making sure ASYNCIFY_IMPORTS is correct, might help. Note that in ASSERTIONS mode we improved debug errors for that pretty recently, not sure if in the last version or since then. > __pyx_pw_11pygame_sdl2_7display_21flip >
