Created attachment 566198 [details] [diff] [review] fix v1.0 It's because jsapi.h assumes that AutoCompartment's size is compiler-dependent, but it's ABI-dependent.
I pushed a fix for this yesterday in bug 693393. Does that work for you?
Yes, thanks. It looks like I last pulled from m-c short after merge.
I'm sorry we put you through the trouble of patching this. :( Glad to hear it's working!
