** Description changed: When zlib acceleration is enabled, gzip fails when given multiple files larger than 5KB. This problem does not happen when running gzip against a single file at a time. It only happens when you provide multiple files as gzip arguments. So this works whether zlib acceleration is enabled or not: for file in file1 file2; do gzip $file ; done But this fails (when zlib acceleration is enabled): gzip file1 file2 The patch to fix this has been accepted upstream: https://git.savannah.gnu.org/cgit/gzip.git/commit/?id=be0a534ba2b6e77da289de8da79e70843b1028cc + + [Impact] + + * With zlib acceleration enabled, attempting to compress multiple files + over 5MB would cause a segmentation fault. + + * The files could still be compressed in separate commands + + [Test Case] + + * Create two files that are larger than 5MB + + * Enable zlib acceleration (z15 hardware required) + + * Run the command gzip <file1> <file2> + + * NOTE: we do not have access to z15 hardware and therefore are relying + on IBM to verify this fix + + [Where problems could occur] + + * Due to lack of testing resources, it's possible the bug has not been + fully fixed, and the segmentation fault could still occur.
