I need a reinterpret_cast because a regular static_cast would be an access as _Fwd_list_node again - at least the FE (or maybe it is fold after all) produces &this->D.1234 in that case which wouldn't fix the issue. But as can be seen in PR41317 there's some mess to sort out before the fix can work. Ugh. Richard. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41316
