Crash Data

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20171116103757 Steps to reproduce: Start monitoring the system CPU and RAM. (I used the command line tool, top.) Visit https://codepen.io/gaearon/pen/ybbQJX?editors=0010 (which is part of the official React tutorial). In line 4 of the JavaScript, delete the "() => " from the onClick property. Watch as the RAM usage of the corresponding Web Content process increases to 100% and the system grinds to a halt. Kill that process to recover responsiveness. Crash report 800cefaa-e9c2-41f6-a8b0-447ff0171130 is an example of this happening. Actual results: The process consumed most of the RAM and the system ground to a halt. Expected results: The "unresponsive script" dialogue should have appeared, giving the opportunity to kill the script by clicking a button.

(In reply to Kohei Yoshino [:kohei] from comment #3) > Bug 1279293 doesn't have the meta keyword actually. That doesn't mean that Bug 1279293 is not a META bug. (In reply to Andrew McCreight [:mccr8] from comment #6) Bug 1279293 > This is a generic signature, so different steps to cause a crash from this > signature should have separate bugs, blocking this bug. I've added the meta keyword to Bug 1279293 (IPCError_ShutDownKill).
