node tests/index.cjs zsh: bus error node tests/index.cjs
const fs = require("fs"); const path = require("path"); WebAssembly.compile(fs.readFileSync(path.join(__dirname, "debug.wasm"))) .then((module) => { return WebAssembly.instantiate(module); }) .then((ins) => { ins.exports._start(); });
(module (type $none_=>_none (func)) (global $~lib/memory/__data_end i32 (i32.const 8)) (global $~lib/memory/__stack_pointer (mut i32) (i32.const 32776)) (global $~lib/memory/__heap_base i32 (i32.const 32776)) (memory $0 0) (table $0 1 1 funcref) (elem $0 (i32.const 1)) (export "_start" (func $assembly/index/_start)) (export "memory" (memory $0)) (func $assembly/index/_start memory.size $0 i32.const 64 i32.mul i32.const 1024 i32.mul i32.const 3 i32.sub i32.load $0 drop ) )
How often does it reproduce? Is there a required condition?
