cat /dev/zero > "/proc/$(pidof vim)/mem"is my favorite dumb way. Clear its memory, wait for the segfault....you can write to program memory? Idk how exactly but that feels like a security risk.
It's your process, why shouldn't you be able to write to it? Vi is certainly doing it...
You do need to be root to do it to arbitrary processes.
dumb way.
Get fancy, add progress bar: pv < /dev/zero > "/proc/$(pidof vim)/mem"
