Incorrect size of inflated file data#33

We've been experiencing a bug with v1.2.11.1_jtkv6.3: inflating a zip file doesn't return the expected amount of data. This could also reproduced this with v1.2.11.1_jtkv6 and the master cloned today.

With a zip file created as follows:

mkdir dir1
head -c 5757690 < /dev/urandom > dir1/file1
head -c 566784 < /dev/urandom > dir1/file2
zip datalessthansize.zip dir1/file1 dir1/file2

Reading the file using this zlib version gives incorrect data for file1:

FileSizeSize inflated dataNotes
file157576905750784???
file2566784566784OK

This behavior is different from the off the shelf zlib v1.2.11:

FileSizeSize inflated dataNotes
file157576905757690OK
file2566784566784OK

Please advise.

                          We've been experiencing a bug with v1.2.11.1_jtkv6.3: inflating a zip file doesn't return the expected amount of data. This could also reproduced this with v1.2.11.1_jtkv6 and the master cloned today.
                          With a zip file created as follows:
                          mkdir dir1
head -c 5757690 < /dev/urandom > dir1/file1
head -c 566784 < /dev/urandom > dir1/file2
zip datalessthansize.zip dir1/file1 dir1/file2

                          Reading the file using this zlib version gives incorrect data for file1:
                          FileSizeSize inflated dataNotes
                          file157576905750784???
                          file2566784566784OK
                          This behavior is different from the off the shelf zlib v1.2.11:
                          FileSizeSize inflated dataNotes
                          file157576905757690OK

                          Please advise.
