// This only happens with console.log. Is this maybe not correcntess-fuzzer ready? Reduced repro - compare ignition vs. ignition_turbo_opt:

print = console.log;

var v1 = 0
function baz() {}
baz.global = this;
function foo(suites) {
  Object.keys(suites).forEach(suite => bar(suites[suite]));
  function bar(suite) {
    Object.keys(suite).forEach(test => suite[test]());
  }
}
var vars = [v1, baz]
for (var j = 0; j < vars.length && j < 7; j++) {
  try {
    foo(vars[j]);
    for (var x = 0; x < 60; x++) {
      print('************************************************************************');
    }
  } catch (e) {
  }

Seems my configuration change has hidden this bug again. This means there was a bug in my change... it shouldn't have led to any behavioral change.

This seems to be a bug in the foozzie runner. When executing the raw commands, everything looks fine.
Labels: -ClusterFuzz-Wrong
We have made a bunch of changes on ClusterFuzz side, so resetting ClusterFuzz-Wrong label.
