One of my coworkers has been suffering this Javascript-related crash for a long time now. It occurs in a WYSIWYG web page editing application driven by jquery and tinymce. It is 100% reproducible every time on both WebKit and Safari. I can't for the life of me find the cause (buried in a very complex set of scripts), so I'm unable to provide the reduction that would surely help, so I'm only left with a crash report. Hopefully it is enough to locate the bug.
Created attachment 39597 [details] Crash report.
Can you please provide steps to reproduce the crash?
I apologize again for not including steps to reproduce. Normally I would create a reduction for you to analyze, but I am unable to do that in this case, nor am I able to provide access to the private application where this is happening. If you're unable to investigate it with the crash report alone, you may close this bug and I will reopen with more information if I am able to produce it.
There isn't enough information in the crash log to be able to investigate this without a reproducible test case.
This has been fixed, so closing.
