Tanks for interested in this but I'm afraid that your patch is
incorrect. mkstemp returns a file descriptor rather than a string
pointer, therefore, the subsequent open() would have undefined behavior.
It looks like that we actually want fd = mkstemp() here.
Note that we may want to bring vendor fixes before making any changes to
reduce duplicated work...
Cheers,
