Seems like this crash can be reproduced on Trunk.  You can reproduce this using SpiderNode on Linux only (the same code works fine on OSX.)

I would appreciate if someone can help us understand why this is happening.  It's very likely that the code creating the context (which crashes) <https://github.com/mozilla/spidernode/blob/master/deps/spidershim/src/v8context.cc#L41> or the runtime <https://github.com/mozilla/spidernode/blob/master/deps/spidershim/src/v8isolate.cc#L48> contains a mistake...

Thanks!
