    Problem Text
    In the source file CAPI/tset/CAPIbase/ftruncate/dtruncate1.c
    the array defined as...

    static off_t size[] = {

    113315, 312947, 257257, 782992, 0, 1024000,
    };

    contains 102 elements. The following line defining NUM_SIZES calculates
    differently for 32 and 64 bit machines.

    #define NUM_SIZES (sizeof(size)/sizeof(size_t))

    On a 32 bit machine, both the sizeof(off_t) and sizeof(size_t) are the same (4)
    producing a result of 102 elements.

    On a 64 bit machine, the sizeof(off_t) is 8 causing the number of elements to be
    204. This causes the test CAPI/tset/CAPIbase/ftruncate/ftruncate1.c to walk
    of the end of the size[] array.

    The #define NUM_SIZES statement should be

    #define NUM_SIZES (sizeof(size)/sizeof(off_t))

    to produce correct results for all machines.
    Test Output
    TEST CASE: truncate

    TEST PURPOSE #1
    A successful call to int truncate(const
    char *path, off_t length) shall cause the regular file
    named by path to have a size of length bytes and
    return 0.
