Thanks Christoph, you are right, it was a bug. After fixing that, all read errors are gone. Now it has only errors for " Use of uninitialised value of size 8", and "Conditional jump or move depends on uninitialised value". The "definitely lost: 0 bytes in 0 blocks", but " possibly lost: 917,938 bytes in 5,594 blocks." I guess I don't need to worry too much about above, right? I am going to further check it. Thank you.
