The following invalid code snippet triggers an ICE on the trunk
when compiled with "-Wall":
===================================
void foo(int i, ...)
{
V v;
__builtin_va_start(v, i);
i = __builtin_va_arg(v, int);
}
===================================
bug.cc: In function 'void foo(int, ...)':
bug.cc:3: error: 'V' was not declared in this scope
bug.cc:3: error: expected ';' before 'v'
bug.cc:4: error: 'v' was not declared in this scope
bug.cc:5: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in operand_equal_p, at fold-const.c:3055
