        * except.c (push_eh_info): Pass the number of fields - 1 down, not
        the exact number of fields.

cuz in finish_builtin_type, its comment sez

   LEN is the number of elements
   in FIELDS minus one, or put another way, it is the maximum subscript
   used in FIELDS.

and its code does

  for (i = 0; i < len; i++)
    {
      layout_type (TREE_TYPE (fields[i]));
      DECL_FIELD_CONTEXT (fields[i]) = type;
      TREE_CHAIN (fields[i]) = fields[i+1];
    }
  DECL_FIELD_CONTEXT (fields[i]) = type;
  DECL_CLASS_CONTEXT (fields[i]) = type;

thus expecting the final ones to be fields[4], not fields[5] (which is
the actual size from 0, not the last field member)

        new_reg_base_value if copying args and REG is a hard register.
        (find_base_value, case PLUS): If either operand of the PLUS is
        a REG, try to get its base value.  Handle base + index and
