I do not know of a simple example, but I have heard there are some example in the C++ grammar where the look-a-head can be as large as possible. Parsers for C(C++) are often not purely grammatical, but also keep a symbol table to resolve these problems. For example, the statement 'a * b;' can either be type definition or a multiplication (with no result) depending on whether 'a' is a type or a variable. Note that in C++ it is possible to defined an *-operator with a side effect.
