I also get this issue when I run the same example code. I have emcc v1.38.12 I was able to look at the required imports of the wasm module to see what was missing: const wasmModule = new WebAssembly.Module(bytecode); console.log("imports", WebAssembly.Module.imports(wasmModule)); This output: imports [ { module: 'env', name: 'table', kind: 'table' }, { module: 'env', name: 'memoryBase', kind: 'global' }, { module: 'env', name: 'tableBase', kind: 'global' }, { module: 'env', name: 'abort', kind: 'function' } ] So perhaps it needs an abort function to be defined. I added a new member to imports.env: abort: _ => { throw new Error('abort');}, I think that needed to be done, but it wasn't the problem, it turns out that WebAssemblyTable needs to have initial set to 2 instead of 0. table: new WebAssembly.Table({ initial: 2, element: 'anyfunc' })

You can always reset your own memory.  You just create a new branch that only has code in it to wipe the memory, switch to that branch, then switch back.

Thanks for reporting, fixed.
