--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:2fb595f8348e164d2f06536ba98322616eeaeeb6 commit r11-734-g2fb595f8348e164d2f06536ba98322616eeaeeb6 Author: Jason Merrill <ja...@redhat.com> Date: Fri May 29 16:55:52 2020 -0400 c++: Template template parameter in constraint [PR95371] any_template_parm_r was assuming that the DECL_TEMPLATE_RESULT of a template will have a suitable TEMPLATE_INFO from which we can look at the generic arguments for that template. But that wasn't true for a template template parameter; this patch makes it so. gcc/cp/ChangeLog: PR c++/95371 * pt.c (process_template_parm): Set DECL_TEMPLATE_INFO on the DECL_TEMPLATE_RESULT. gcc/testsuite/ChangeLog: PR c++/95371 * g++.dg/cpp2a/concepts-ttp1.C: New test.
