What terminal are you using that crashes so often? I’ve used Linux and Mac terminals for ages and cannot remember one terminal crash.
I use urxvt on Linux, and I don't have any problems with it.
Edit: I should also mention that I see plenty of non-crashing, non-hanging bugs with iTerm2 that look like memory misuse to me: split-workspace mode (tiled with a text editor) causes wonky graphical errors, and I've seen what looked like buffer reuse artifacts when switching between monitors.
I cannot recall any crashes in alacritty, gnome-terminal, xfce-terminal or the legacy windows console for other terminals I've used a decent amount.
