add_list_candidates has logic to reject designated initialization of a non-aggregate type, but this is inadvertently being suppressed if the type has a list constructor due to the order of case analysis, which in the below testcase leads to us incorrectly treating the initializer list as if it's non-designated. This patch fixes this by making us check for invalid designated initialization sooner. PR c++/109871 gcc/cp/ChangeLog: * call.cc (add_list_candidates): Check for invalid designated initialization sooner and even for types that have a list constructor. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/desig27.C: New test.
