Created attachment 470651 [details] [diff] [review] Fix. After bug 578547 (and related bugs) landed we now allocate a jsval on the heap for each jsval in arguments when calling from JS into C++. This allocation happens in XPCConvert::JSData2Native() in the T_JSVAL case, if useAllocator is set. We can, however, avoid this allocation in the case where we simply have the jsval argument passed into XPConnect, but due to the XPCConvert API we can't call into it in those cases. Patch attached showing how this can be done. This is however not a common path in our code, so there's no real urgency to make this change...
