--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <[email protected]>: https://gcc.gnu.org/g:dcaafedee8a34f9ad60ac4d47ffe7529959028d2 commit r17-4153-gdcaafedee8a34f9ad60ac4d47ffe7529959028d2 Author: Jakub Jelinek <[email protected]> Date: Fri Sep 11 09:31:57 2026 +0200 c++: Fix up tsubst_splice_expr [PR127276] The following testcase is incorrectly rejected. While when parsing the splice expressions outside of templates we call finish_id_expression -> finish_id_expression_1 -> convert_from_reference, in tsubst_splice_expr that doesn't happen and so build_x_array_ref is called with the PARM_DECLs of REFERENCE_TYPE rather than INDIRECT_REFs of those. The following patch adds the convert_from_reference call. 2026-09-11 Jakub Jelinek <[email protected]> PR c++/127276 * pt.cc (tsubst_splice_expr): Call convert_from_reference if not member access and SPLICE_EXPR is a splice expression. * g++.dg/reflect/pr127276.C: New test.
