Hey there!
I am trying to kick off a v8 instance in a separate thread. But when I do that,
I get a crash about the used isolate. Here is the debugger output:
$ lldb ./out/Debug/node
Current executable set to './out/Debug/node' (x86_64).
(lldb) run
Process 1163 launched: './out/Debug/node' (x86_64)

# Fatal error in ../../deps/v8/src/v8threads.cc, line 48
# CHECK(isolate != __null) failed

And the respective code:
struct _Args_t { int arg_c; char** arg_v; } Args;
void* runner(void* data) {
cout << "Args: " << Args.arg_v[0] << endl;
node::Start(Args.arg_c, Args.arg_v);
return NULL;
}
int main(int argc, char *argv[]) {
// Init the struct.
Args.arg_c=argc;
Args.arg_v=(char**)argv;
cout << "..." << endl;
pthread_t thatOtherThread;
pthread_create(&thatOtherThread, NULL, runner, NULL);
pthread_detach(thatOtherThread);
sleep(5);
return 0;
}
Any help would be apriciated! ^_^
Kind regards, Ingwie
