New Revision: 269512

URL: https://gcc.gnu.org/viewcvs?rev=269512&root=gcc&view=rev
Log:
	PR c++/88419 - C++17 ICE with class template arg deduction.

Just like in make_constrained_auto, we need to defer setting TYPE_CANONICAL
until we've set fields that will affect structural_comptypes.

	* pt.c (make_template_placeholder): Set TYPE_CANONICAL after
	CLASS_PLACEHOLDER_TEMPLATE.
