won't it be too verbose?  maybe hide it behind a flag?

When used in our tests this reports failures so hopefully it won't be too
verbose. When used as a javascript shell printing full trace is a sensible thing
to do.

+      const char* stack_trace_string = ToCString(stack_trace);
+      printf("%s\n", stack_trace_string);
