Compiled async generator for-await value getter bypasses the local catch #3629
Description
const iterable = {
[Symbol.asyncIterator]() {
return {
next() { return { done: false, get value() { throw new Error('step'); } }; },
return() { console.log('unexpected close'); return { done: true }; }
};
}
};
async function* run() {
try { for await (const value of iterable) yield value; }
catch (error) { yield error.message; }
}
run().next().then(result => console.log(result.value, result.done),
error => console.log('rejected', error.message));Node prints step false. On 72455db66, SharpTS compilation with --no-tsconfig --noLib --compile --verify passes IL verification, but the saved DLL prints rejected step.
The error from reading the iterator result's value should reach the generator's local catch. The emitted for await path reads value outside its exception router. Found while verifying #3614.
