Version First unspecified

This was reported as KPhotoAlbum bug 512199 but is actually a bug in KZip.
SUMMARY
If KZip is asked to zip files of size ~4GB or more, it will create an invalid
zip file.
STEPS TO REPRODUCE
$ du -sh ~/images/2017
5.4G /home/me/images/2017
$ ~/kde/build/karchive/bin/kziptest create test.zip ~/images/2017/*
$ echo $?
0
$ ~/kde/build/karchive/bin/kziptest print-all test.zip
Opening zip file
Could not open "test.zip" for reading. ZIP file doesn't exist or is invalid:
"Invalid ZIP file. Unrecognized header at offset 369583458"
$ unzip -t test.zip
Archive: test.zip
warning [test.zip]: 4294967296 extra bytes at beginning or within zipfile
(attempting to process anyway)
file #1: bad zipfile offset (local header sig): 4294967296
(attempting to re-compensate)
testing: filename.JPG OK
error: not enough memory for bomb detection
At least one error was detected in test.zip.
OBSERVED RESULT
KZip silently fails to create a valid zip file.
EXPECTED RESULT
KZip should create a valid zip file, or report an error to the application if
it is unable to do so.
