New issue 27252 by yu...@chromium.org: DevTools renderer crashes in debug mode on attempt to inspect devtools http://code.google.com/p/chromium/issues/detail?id=27252 What steps will reproduce the problem? 1. Open the attached file. 2. Open first DevTools window. 3. Move mose over 'Div Text' to make script pause. 4. Open DevTools window for the first DevTools window, open debugger_agent.js and set a breakpoint in devtools.DebuggerAgent.prototype.resolveChildren in requestLookup_ callback. 5. Now return to the first DevTools window and expand 'handler' variable. 6. When execution is stopped on the breakpoint in the second DevTools window click in console command line. What is the expected output? You can type an expression. What do you see instead? Both DevTools renderers crash.
