Re: [v8-users] Isolate->Dispose() causes crash only when Math.random() is used

[Jochen Eisinger]

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.

Yep, that was it! Thanks for your help Jochen!

[v8-users] 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
