--- Comment #5 from erezg at microsoft.com ---
Unfortunately I don't have a test page, as this is an internal page within the PowerBI.com website with tons of JavaScript that fetches data from a backend. But I'll see if I can create a static, smaller page which reproduces.

I managed to get this crash while debugging the MiniBrowser with XCode built on debug. I believe you are right, and we try to call createFontFamilyValue() with a null string. The JSC::PropertyName was "fontFamily".

Anything else that I can check with the XCode debugger to help?
