It'd be easier to comment on it if you sent it by email.

Anyway, why did you remove the condition on hash_free_result?
We free the result if it's not needed, not to clear the previous
hash. So by doing it uncondtionally you will simply end up
freeing and reallocating the result for no good reason.
