Stack smashing protect failure! ()

[Gan-Erdene]

Most of the time my device works well, but after a day, it stops and shows an error. Turning it off and on again fixes it for a day. What's the difference between a soft reset and a hard reset? What might be causing this issue?

Probably something like allocating a buffer on the stack, then overflowing that buffer.
