If the device is turned off, usually by syndaemon to disable the touchpad while the typing, the touch state will not be updated with the latest hardware state changes. If a touch begins while the device is off and ends while the device is on, then the touch count will be decremented without any previous increment. A similar effect will occur if the device is on when the touch begins, but off when the touch ends.
If the touch count goes negative, the index into the touch slot mask array will be out of bounds. This can corrupt memory and cause random crashes.
