    lib/test_rhashtable: Make test_insert_dup() allocate its hash table dynamically · fc42a689
    Bart Van Assche authored
    The test_insert_dup() function from lib/test_rhashtable.c passes a
    pointer to a stack object to rhltable_init(). Allocate the hash table
    dynamically to avoid that the following is reported with object
    debugging enabled:
    ODEBUG: object (ptrval) is on stack (ptrval), but NOT annotated.
