The stack trace suggests a stack overflow happened (the call to Isolate::StackOverflow() from Genesis::Genesis) while creating the debug context. It suggests the thread's stack is too small but that could be a red herring because you don't appear to be using a v8::Locker to synchronize access to the isolate. -- -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
