[Haskell-beginners] Query regarding an unusually behaving code

Bellow is my code for returning a list of digits given an integer.I'm unable to find any bug in it but somehow it crashes any computer I run it on when I try to calculate digs 100.Please tell me bug in my code. let digs 0 =[0] let digs x = (digs (x `div` 10)) ++ [(x `rem` 10)] digs 100 Thanks Abhishek
