--- Comment #8 from seurer at gcc dot gnu.org --- Here is the list of the current failures for trunk (they all fail with gcc 12 too). I did not include the xtreme-header ones as those are flakey and fail elsewhere, too (there are several PRs open about them). FAIL: g++.dg/modules/binding-1_a.H -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/binding-1_a.H -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/binding-1_a.H -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/binding-1_b.H -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/binding-1_b.H -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/binding-1_b.H -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/global-3_a.C -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/global-3_a.C -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/global-3_a.C -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/hello-1_a.C -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/hello-1_a.C -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/hello-1_a.C -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/iostream-1_a.H -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/iostream-1_a.H -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/iostream-1_a.H -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99023_b.X -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99023_b.X -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99023_b.X -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99166_a.X -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99166_a.X -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99166_a.X -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_a.X -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_a.X -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_a.X -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_b.X -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_b.X -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/pr99425-2_b.X -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/string-1_a.H -std=c++17 (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/string-1_a.H -std=c++2a (internal compiler error: in type_node, at cp/module.cc:8878) FAIL: g++.dg/modules/string-1_a.H -std=c++2b (internal compiler error: in type_node, at cp/module.cc:8878)
