Description of problem: Selecting many lines of text(shift-click a range, or select-all) in gnome-terminal can result in a crash. Requires > 100,000 lines, possibly millions (upstream bug is a bit unclear if those are lines/rows or what). Version-Release number of selected component (if applicable): VTE 0.60.3 How reproducible: Always, as described Steps to Reproduce: See upstream bug for details. Actual results: Crash Expected results: No crash Additional info: Difficult to reproduce by default in Fedora's GNOME Terminal: neither the menu bar (to get to an Edit -> Select All option) nor a shortcut for Select-All exist. So you've got quite a lot of scrolling to shift-click select a range big enough to trigger the bug. Also by default, there is a 10,000 line scrollback limit, which isn't enough to trigger the bug. The problem is not limited to Fedora 34, it seems to be quite an old known bug.
Upstream has a workaround for the crash, by preventing large selections. This workaround is being reverted in Fedora, i.e. if you make really large selections, you might get a crash.

Usually things don't need to go in both release notes and common bugs. One or the other is good.
