Hello all,


I have found a conflict in parsing C99 which arises from the fact that
after a mult_expr a '*' (according to bison) can come up which means
that it can either reduce mult_expr or shift the '*' for yet another
multiplication.


Now, * comes up as a unary operator and in the pointer definition but
I can't find how or where they can follow a multiplication. Can
someone let me know either how to solve this shift/reduce conflict or
give me a concrete example where a * comes after a multiplication and
is not a multiplication operator?


Cheers,
