Package: cups
Version: 2.3.3-1~bpo10+1
Followup-For: Bug #961345
Dear Maintainer,
I'm running the Testing version of cups recompiled for Buster. I'm seeing the
same "invalid pointer" issue as the reporter.
Backtrace for a coredump is below. Please let me know if there's any other
information I can provide in order to help get a solution for this issue. It's
disrupting our printing significantly:
