Description
This code
seed.js
try {
a = 1;
let a = 2; // ReferenceError (dynamic)
} catch (error) {
console.log("Test 1 successful");
}
get's translated from Fuzzilli to
lifted.js
try {
a = 1;
} catch(e2) {
console.log("Test 1 successful");
}
Therefore "Test 1 successful" will not be printed.
Probably not a big issue but I thought it would be worth documenting
