Freeze game on multiple touch

My game has a number of functions that are called consecutively.
The first function is called as soon as you get a touch (or a tap, I tried both solutions).
It works in 99% of cases.

Assuming you do a series you touch (or tap) infinitely fast after some seconds the game does not crash but freeze.

Why? Not absolutely understand why.
