unzOpenInternal() return UNZ_BADZIPFILE #825

I was tried to use contrib/minizip to unzip a zip archive which generated by contrib/minizip/minizip.c demo, but unzOpen2_64() return NULL; I found unz64local_SearchCentralDir64() return 0 and unzOpenInternal() return UNZ_BADZIPFILE when traced in unzOpen2_64() at here:

/** unzip.c */
717:        if ((number_entry_CD!=us.gi.number_entry) ||
718:            (number_disk_with_CD!=0) ||
719:            (number_disk!=0))
720:            err=UNZ_BADZIPFILE;

Can any one help? thanks.
