This piece of legal code gives an ICE with 3.4. This is a regression from 3.3:
--------- cut --------
int x = y ;
int y ;
--------- cut --------
reduce.3797.out:1: error: `y' undeclared here (not in a function)
reduce.3797.out:2: internal compiler error: tree check: expected class 'd', have 'x' (error_mark) in any_external_decl, at c-decl.c:1553
