    Problem Summary Truncation happen when convert a pointer to integer
    Problem Text We come across a problem in the test
    ?/tset/CAPI.os/mman/mmap/T.mmap 21?.

    In CAPI.os/mman/mmap/mmap21.c line 176, there is a sentence:

    ask_addr = (int *)((int)ask_addr-1);

    A pointer is transferred to int type. Because our OS is 64 bits,
    the pointer takes up 64 bits. But the int type takes up 32bits.
    So we thought the test do not consider about this situation.
