--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Yea, the fold call there is puzzling. Even a change in r67189 (old one!) had: - /* Don't fold a COMPONENT_EXPR: if the operand was a CONSTRUCTOR (the - only time it will fold), it can cause problems with PLACEHOLDER_EXPRs - in Ada. Moreover, it isn't at all clear why we fold here at all. */ - if (TREE_CODE (t) != COMPONENT_REF) - t = fold (t); Does anything break if we get rid of the fold call?
