--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:4ef4c88af7007ff0563e65269e1807b1ba30085d commit r8-10472-g4ef4c88af7007ff0563e65269e1807b1ba30085d Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Mar 19 12:22:47 2020 +0100 c++: Fix up handling of captured vars in lambdas in OpenMP clauses [PR93931] Without the parser.c change we were ICEing on the testcase, because while the uses of the captured vars inside of the constructs were replaced with capture proxy decls, we didn't do that for decls in OpenMP clauses. With that fixed, we don't ICE anymore, but the testcase is miscompiled and FAILs at runtime. This is because the capture proxy decls have DECL_VALUE_EXPR and during gimplification we were gimplifying those to their DECL_VALUE_EXPRs. That is fine for shared vars, but for privatized ones we must not do that. So that is what the cp-gimplify.c changes do. Had to add a DECL_CONTEXT check before calling is_capture_proxy because some VAR_DECLs don't have DECL_CONTEXT set (yet) and is_capture_proxy relies on that being non-NULL always. 2020-03-19 Jakub Jelinek <ja...@redhat.com> PR c++/93931 * parser.c (cp_parser_omp_var_list_no_open): Call process_outer_var_ref on outer_automatic_var_p decls. * cp-gimplify.c (cxx_omp_disregard_value_expr): Return true also for capture proxy decls. * testsuite/libgomp.c++/pr93931.C: New test.
