Isolate->Dispose() causes crash only when Math.random() is used

[George Corney]

Hey,

I'm struggling to get to the bottom of this one

The crash occurs with a slightly modified version of the hello-world.cc sample, I've separated the initialization and execution into one function and the dispose calls into another. If the executed javascript contains Math.random(), the app crashes with 'Segmentation fault: 11' when isolate->Dispose() is called. If isolate->Dispose() is called from within the initialization function then there is no crash.

Here's the code https://gist.github.com/haxiomic/502227a9f0c606cd6117

The crash log is in a comment below

I'm keen to know if i'm doing something wrong in how I'm separating the initialization and dispose calls or if this is a bug with Math.random()

I'm running OS X 10.11.3 and building with V8 with hash e709aa2

you stack-allocate the ArrayBufferAllocator, so it'll get destructed at the end of the Initialize() method.

You should allocate it on the heap instead, so it outlives that method.
