Bug 31259 – Web Inspector: Crash when inspecting WebCore\manual-tests\inspector\dom-mutation.html

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Alexander Pavlov (apavlov)]

Steps to reproduce:

1. Open WebCore\manual-tests\inspector\dom-mutation.html and open the Web Inspector's Elements panel
2. Expand the iframe body node (html/body/div[1]/iframe/html/body) in the elements tree. Watch the contents changing after the iframe content updates.
3. Click the "Test frame 2" button in the inspected page.

The following crash occurs:
