Sorry, schoolboy error - that last one is just your average unused false positive.

That's weird - I can. Hopefully this isn't OS-dependent...
I tried a few node versions with various options and could not get the first test case to fail. Once you reduce the test case I can try again.

My current test case:
issue_2630: {
options = {
collapse_vars: true,
inline: true,
passes: 2,
reduce_funcs: true,
reduce_vars: true,
sequences: true,
side_effects: true,
unused: true,
}
input: {
var c = 0;
(function() {
while (f());
function f() {
var a = function() {
var b = c++, d = c = 1 + c;
}();
}
})();
console.log(c);
}
expect: {
var c = 0;
(function() {
while (c++, void (c = 1 + ++c)) ;
})(),
console.log(c);
}
expect_stdout: "2"
}
I saved your reduced test case, renamed it and tried to run it with node and got this baffling result:
$ cat test1reduced.js | node
Galloping...
Tommy the Palomino moved 34m.
It turns out I had an old test program by the same name (I'm not very inventive) and the file move had failed and I didn't see the error.

The reduced test case does indeed fail here:
$ cat test1b.js | node
2
$ cat test1b.js | bin/uglifyjs --toplevel -c passes=9 | node
3
while (f()); function f() {
Was this a forward call generated by the most recent ufuzz changes?

Yup - and single-use to boot 😎

I thought I'd reduce the third test case, but it appears similar to the one already reduced above. You might make a test of it anyway.
$ cat tc3.js
var c = 0;
!function() {
while (f()) {}
function f() {
var not_used = function() {
c = 1 + c;
}(c = c + 1);
}
}();
console.log(c);
$ cat tc3.js | node
2
md5-83a03272ee61cfa3b07dc28bb990ddaa
$ cat tc3.js | bin/uglifyjs -c passes=2 | node
3
It'd be easier if a new issue was created for each fuzz failure.

Test case 5 reduced:
$ cat tc5.js
var x = 2, a = 1;
(function() {
function f1(a) {
f2();
--x >= 0 && f1({});
}
f1(a++);
function f2() {
a++;
}
})();
console.log(a);
```
$ cat tc5.js | node
5
$ cat tc5.js | bin/uglifyjs -bc | node
2
```js
$ cat tc5.js | bin/uglifyjs -bc
var x = 2, a = 1;
!function() {
function f1(a) {
a++, --x >= 0 && f1({});
}
f1(a++);
}(), console.log(a);
Test case 4 reduced:
$ cat tc4.js
var x = 3, a = 1, b = 2;
(function() {
(function f1() {
for (; --x >= 0 && f2();) {}
}());
function f2() {
a++ + (b += a);
}
})();
console.log(a);
```
$ cat tc4.js | node
2
$ cat tc4.js | bin/uglifyjs -bc | node
3
```js
$ cat tc4.js | bin/uglifyjs -bc
var x = 3, a = 1, b = 2;
!function() {
!function() {
for (;--x >= 0 && void (a++, b += ++a); ) ;
}();
}(), console.log(a);
Thanks for the test cases – I'm under the impression that they are all of the same bug, hence the single report.
Though now that I have to scroll through it, I think I shall make a separate issue for each ufuzz report in the future...

do/while test variation:
$ cat tc3c.js
var c = 1;
!function() {
do {
c *= 10;
} while (f()) {}
function f() {
return function() {
return (c = 2 + c) < 100;
}(c = c + 3);
}
}();
console.log(c);
```
$ cat tc3c.js | node
155
$ cat tc3c.js | bin/uglifyjs -bc passes=2 | node
188
```js
$ cat tc3c.js | bin/uglifyjs -bc passes=2
var c = 1;
!function() {
do {
c *= 10;
} while (c += 3, (c = 2 + (c += 3)) < 100);
}(), console.log(c);
I'm under the impression that they are all of the same bug, hence the single report.
Did that impression hold true?
What's the current fuzz count or will you reset?
kzc

Did that impression hold true?
Sort of - there are three different bugs, but the failed cases overlap between what they've tripped over :sweat:
What's the current fuzz count or will you reset?
I always reset when master got (code) changes.
alexlamsl

... and without #2636 the fix for this issue would trip over a whole can of worms as well.
alexlamsl
on 23 Dec 2017
What's the new fuzz iteration target before release?
kzc
on 23 Dec 2017
I'm aiming for 5MFuzz - hopefully the extra day is going to help :wink:
