Cannot reproduce the crash on Linux.

Before https://invent.kde.org/utilities/konsole/-/commit/5128781a824c26dc2746650fea0ae9f95861b9d8 , zcatting the attached file takes a long time. After that commit, it's fast.

Cygwin's konsole version is v17.12.3, which is ancient. All KDE packages in Cygwin are orphaned, see https://cygwin.com/cygwin-pkg-maint and https://cygwin.com/pipermail/cygwin-apps/2020-March/039877.html
