It could only deallocate it if the global reference was changed and all attempts to change the global reference should go through the same spinlock. The signal handler should always be given the "second reference" no matter what. Or, since you're using spinlocks to guard all changes to the global reference, you could just change the global reference to a plain old pointer which might make it more obvious. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
