            Bug ID: 172432
           Summary: Web Inspector: Using "break on all exceptions" when
                    throwing stack overflow hangs inspector
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sbarati at apple.com
                CC: inspector-bugzilla-changes at group.apple.com

e.g, if I enable "Break on all exceptions" and run this program, web inspector hangs for me. My guess is it's trying to do stuff above the JS stack at the time of stack overflow, which if true, is definitely not allowed.

```
let arg = 20
function f() {
    f(arg);
}

function recurse() {
    try {
        f();
    } catch(e) {
    }
    setTimeout(recurse, 0);
}
recurse();
```
