Stack overflow when invalid binary expression

[Jomy10]

Stack overflow will happen when an invalid binary expression is given. For example:

a := 5 noot!(a)

Since there's no semicolon or new line between 5 and noot!(a), these are seen as one expression. The first value of the expression is an integer and there is more to the expression, so it thinks it is a binary expression.

This however, is not a valid binary expression and the parser stack overflows.
