the difference, for the latter and for more complex cases, is that
adjust_temp_type calls cp_fold_convert which ends up returning a
NOP_EXPR (eg, build in fold_convert_loc).
Perhaps we should address this in adjust_temp_type, either by ignoringthe conversion to a canonically equivalent type or by directlychanging the type of the ADDR_EXPR.

Ok. I didn't tell you in my first message that I already tried changingthe 'TREE_TYPE (temp) == type' to 'same_type_p (TREE_TYPE (temp), type)'and it works for the simple case I posted, but it doesn't in morecomplex cases, involving templates too. Thus something more complex inadjust_temp_type, I suppose...


Paolo.
