Narrowed test case:
$ cat test.js
var a = 1, c = 0;
try {
} catch (e) {
a[a] = 0;
}
try {
throw a;
} catch (e) {
try {
throw 0;
} catch (a) {
(e && e[!function() {
c++;
}()]);
}
}
console.log(null, a, c);

@kzc just to confirm, is 2120.js the input from ufuzz.js or my reduced test case from https://github.com/mishoo/UglifyJS2/issues/2120#issuecomment-309278747 ?

2120.js is same as test.js in https://github.com/mishoo/UglifyJS2/issues/2120#issuecomment-309278747
