For C++ 26 P2552R3 I went through all the spots (except modules) where attribute-specifier-seq appears in the grammar and tried to construct a testcase in all those spots, for now for [[deprecated]] attribute. This is the second issue I found. The comment already correctly says that attributes after closing ] appertain to the array type, but we were appending them to returned_attrs, so effectively applying them to the declarator (as if they appeared right after declarator-id). 2024-08-20 Jakub Jelinek <jakub@redhat.com> PR c++/110345 * decl.cc (grokdeclarator): Apply declarator->std_attributes for cdk_array to type, rather than chaining it to returned_attrs. * g++.dg/cpp0x/gen-attrs-82.C: New test. * g++.dg/gomp/attrs-3.C (foo): Expect different diagnostics for omp::directive attribute after closing square bracket of an automatic declaration and add a test with the attribute after array's declarator-id.
