[Bug 1901528] [NEW] [Ubuntu 20.10] - When zlib acceleration is enabled, gzip fails when given multiple files larger than 5KB (gzip)

[bugproxy]

Public bug reported:

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
