Empty productions are supposed to be assigned the start attributes of the lookahead token. Currently, this happens by assigning above the current stack position when the token it read. This fails in a situation where we first reduce an empty production higher up in the stack, and then again reduce an empty production lower in the stack, without consuming the lookahead token in the meantime. Fix this by moving the assignment into the reduction phase. We also need to do this for error productions, which are effectively empty. |
