Error description

  • For 64 bytes bucket memory, if the memory is ended with address
    0xFC0, Its internal house keeping data structure is not marked
    correctly. As the result, we can't determine if the memory
    ended with 0xFC0 is malloced or freed.

Problem summary

  • For 64 bytes bucket memory, if the memory is ended with address
    0xFC0, Its internal house keeping data structure is not marked
    correctly. As the result, we can't determine if the memory
    ended with 0xFC0 is malloced or freed.
    

Problem conclusion

  • ku_police_debug and ku_free_debug are all 64-bit in size.
    We'd make sure when it does left shift operation, it doesn't
    go over the 64 bit size boundary.
