Local fix

Problem summary


    

  • The problem is caused due to the data loss in conversion from
datatype long long to unsigned int for the variable that keeps
track of central header of a zip entry.

    



Problem conclusion


    

  • This defect will be fixed in:
6.0.0 SR14
6.0.1 SR6
.
datatype is changed to long long in zip code with which the
central header position is maintained correctly even when zip
size is beyond 4GB.
