Like this ?  Lightly tested.  A full bootstrap and regression test is
under way.

Thanks.

gcc/cp/

	PR c++/48574 * class.c (fixed_type_or_null): Use
	type_dependent_p_push to test if the instance has a dependent
	initializer.

gcc/testsuite/

	PR c++/48574
	* g++.dg/template/dependent-expr8.C: New test case.
