Description David Auer (2nd Account) 2022-03-21 16:35:43 UTC 
Description of problem:
Steps to reproduce:
1. Run tmux
2. Enter command mode (Ctrl+b, ':')
3. Hold Ctrl and hit Up-Arrow 3 times (the other 3 arrow directions work, too)

Tmux will crash printing [server exited unexpectedly] and leaving a garbled terminal.

This is always reproducible on Fedora 35 with versions tmux-3.2a-2.fc35 and tmux-3.2a-3.fc36.

It is not reproducible on Debian 11 with tmux-3.1c-1+deb11u1.

Thanks for looking into it!

I believe this should be easy to reproduce, therefore I removed backtrace and environ to be on the save side regarding leaking any sensitive data. Let me know if this is not reproducible or in case you need the backtrace for any other reason I can't think of.
The gist is also in this abrt report: https://retrace.fedoraproject.org/faf/reports/270639/

A colleague just told me that 3.4 compiled from source works fine.

Hi David, thanks for your report.
For while, the 3.3 release is still an Release Candidate version, so for now I prefer to wait for a final 3.3 release to proceed with the update.
