The test case is incorrect. PTHREAD_DESTRUCTOR_ITERATIONS specifies a
lower limit on the number of iterations performed. It is explicitly not
a hard limit. To quote POSIX:

Calling pthread_setspecific() from a thread-specific data destructor
routine may result either in lost storage (after at least
PTHREAD_DESTRUCTOR_ITERATIONS attempts at destruction) or in an infinite
loop.
