Currently the pthread allocation for each array item is based on the size of a pthread_t pointer and should be the size of the pthread_t structure, so the allocation is under-allocating the correct size. Fix this by using the size of each element in the pthreads array.

Static analysis cppcheck reported: tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer 'threads' used instead of size of its data. [pointerSize]
