I can confirm this issue, AND it also crashes other tabbed windows in Chrome 66 at the same time with either "Aw, Snap!" or "Cant open this page" errors

Yep same here as mentioned above. Worked for years till 66. All other browsers no issue. Just Chrome.

Wild stab... is this something to do with SetTimeout() and the stack?
Each call to setTimeout() is now being pushed onto the stack, I do not see this with Firefox, the stack there only contains the last async call to update() in the code below. Chrome 66 the stack just grows continuously.
<!DOCTYPE HTML>
<html lang="en">
<head>
<script>
var count = 0;
function update() {
document.getElementById('update_me').innerHTML = count;
count++;
setTimeout(update, 1);
}
setTimeout(update, 1);
</script>
</head>
<body>
<div id="update_me"></div>
</body>
</html>

Thanks for filing the issue. As per the provided crash id in C#0, seems this issue is similar to #838503 hence merging into it. Feel free to undup if it is not similar.

I do not think this is a duplicate of 838503, the crash happens when the dev tools are not running.

I am also getting this issue on Cumulus MX (http://localhost:8998/index.html). I am running Chrome on a Mac High Sierra 10.13.4 (17E202). The Cumulus MX page reloads fine every time manually but then 2-3 minutes later it goes Aw Snap again.

838503 is specific to DevTools. Unmerging.
