Created attachment 511388 [details] Minimal test source Description of problem: The zlib extension minizip (package minizip and minizip-devel) does not properly identify size overflow conditions in zip64 files when the host system is actually 64-bit native. Version-Release number of selected component (if applicable): 1.2.5-2.fc14 How reproducible: Consistently Steps to Reproduce: 1. Install package minizip-devel 2. Run attached run_test.sh script to create large zip file and attempt to read. 3. Observe three failures. Actual results: The minimal test program fails to detect large file size correctly, and fails when opening files beyond 4GiB point in Zip archive file. Failure output "Contains 'large.test', size 0xFFFFFFFF bytes". Failure output "opening file failed: -103" Failure output "closing file failed: -102" Expected results: Expect output "Contains 'large.test', size 0x119400000 bytes". Expect output "opening file succeeded" Expect output "closing file succeeded" Additional info: See attached test program for detailed failure info and attached patch for a possible fix.
