+Subject: [PATCH] c++: alias_ctad_tweaks ICE w/ inherited CTAD [PR119687]
+
+With inherited CTAD the set of guides may be a two-dimensional overload
+set (i.e. OVERLOADs containing OVERLOADs) so alias_ctad_tweaks (which
+also handles the inherited CTAD transformation) needs to use the 2D-aware
+lkp_iterator instead of ovl_iterator.  Actually, we might as well use
+the more idiomatic lkp_range here.
+
+	PR c++/119687
+
+gcc/cp/ChangeLog:
+
+	* pt.cc (alias_ctad_tweaks): Use lkp_range / lkp_iterator
+	instead of ovl_iterator.
+
+gcc/testsuite/ChangeLog:
+
+* g++.dg/cpp23/class-deduction-inherited8.C: New test.
