Here, alias_ctad_tweaks expect tsubst_decl of a FUNCTION_DECL to return a FUNCTION_DECL. A reasonable expectation, but in this case we were replacing the template args of the class-scope deduction guide with equivalent args, so looking in the hash table we found the partial instantiation stored when instantiating A<int>, which is a TEMPLATE_DECL. It's fine for that to be what is stored, but tsubst_function_decl should never return it. PR c++/105655 gcc/cp/ChangeLog: * pt.cc (build_template_decl): Add assert. (tsubst_function_decl): Don't return a template. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/class-deduction-alias13.C: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
