Thou shalt not free(3) memory dirname(3) returned
On Linux basename() and dirname() return a pointer within the string
passed as argument. On BSD flavors, basename() and dirname() return
static storage, or pthread specific storage. Both behaviour are
compliant, but calling free on the result in the second case is a bug.
BUG: 764655
