https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105842 --- Comment #4 from CVS Commits --- The releases/gcc-12 branch has been updated by Patrick Palka : https://gcc.gnu.org/g:5d6286903f325a7a85e5ab1d04ba942d33d755bc commit r12-8605-g5d6286903f325a7a85e5ab1d04ba942d33d755bc Author: Patrick Palka Date: Wed Jul 13 14:01:28 2022 -0400 c++: dependence of constrained memfn from current inst [PR105842] Here we incorrectly deem the calls to func1, func2 and tmpl2 as ambiguous ahead of time ultimately because we mishandle dependence of a constrained member function from the current instantiation. In type_dependent_expression_p, we already consider dependence of a TEMPLATE_DECL's constraints (via uses_outer_template_parms), but neglect to do the same for a FUNCTION_DECL (such as that for func1). And in satisfy_declaration_constraints, we give up if _any_ template argument is dependent, but for non-dependent member functions from the current instantiation (such as func2 and tmpl2), we can and must check constraints as long as the innermost arguments aren't dependent. PR c++/105842 gcc/cp/ChangeLog: * constraint.cc (satisfy_declaration_constraints): Refine early exit test for argument dependence. * cp-tree.h (uses_outer_template_parms_in_constraints): Declare. * pt.cc (template_class_depth): Handle TI_TEMPLATE being a FIELD_DECL.
