fatal: tty_clamp_area: y too big, 4294967295 > 0

[Adam Cooper]

When in main-horizontal layout, in one of the lower panes, running an application that "pages" (e.g., ps, git log, git reflog), quitting the application crashes tmux with a "lost server" message. The debug log ends in fatal: tty_clamp_area: y too big, 4294967295 > 0

I'm running tmux 2.9a, zsh 5.3, macOS Mojave 10.14.4. I'll paste the end of the debug log below. Thanks!
