--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:fe0f9ef823dda3205638a2f23d08eb7d0bc497b9 commit r10-9855-gfe0f9ef823dda3205638a2f23d08eb7d0bc497b9 Author: Jason Merrill <ja...@redhat.com> Date: Tue Apr 13 12:33:39 2021 -0400 c++: generic lambda in template fn with DMI [PR100054] get_nsdmi instantiates default member initializers on demand. It tries to push into the context of the class before doing so, so access checking works properly, but since my patch for 90479 not for local classes. We should only be doing this when any template parameters have arguments. But in this case, we get here while regenerating a generic lambda, so processing_template_decl is true, even though the class and its DMI are non-dependent at this point. And so we crashed. So let's do more of the pushing into the context of the class even for local classes. gcc/cp/ChangeLog: PR c++/100054 PR c++/90479 * init.c (get_nsdmi): Do more context adjustment for local classes. gcc/testsuite/ChangeLog: PR c++/100054 * g++.dg/cpp1y/lambda-generic-local-class1.C: New test.
