Subject: [C++ Patch] PR 54575

Hi,

here we crash because strip_typedefs while processing _RequireInputIter calls make_typename_type which returns error_mark_node (# line 3281). Thus I'm simply checking for result == error_mark_node right after the switch (in the switch finish_decltype_type could also return error_mark_node, for example) and before handling the alignment (where we are crashing now). Issue seems rather straightforward.

Tested x86_64-linux.

Thanks,
Paolo.

PS: I'm also attaching a patchlet for a couple of hard errors in make_typename_type not protected by (complain & tf_error) spotted in make_typename_type.
