Hi!When a C++17 inline static data member has a redundant out-of-class deprecated redeclaration, we can end up with 2 DW_TAG_variable in DW_TAG_compile_unit, one DW_AT_declaration and one with DW_AT_specification pointing to it (the latter emitted for the redeclaration), before gen_member_die can do its job. In there we want to move the declaration DIE into the class and have a CU child DW_TAG_variable that has DW_AT_specification pointing to it. But in this case we've put the DIE with DW_AT_specification into the hash table and gen_member_die ICEs in splice_child_die. The following patch handles that case gracefully, by moving the DW_AT_declaration DIE into the class instead of trying to move the DW_AT_specification one, and by making sure we don't create yet another DIE with DW_AT_specification because we already have one. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2017-03-29 Jakub Jelinek <ja...@redhat.com> PR debug/80234 * dwarf2out.c (gen_member_die): Handle C++17 inline static data members with redundant out-of-class redeclaration. * g++.dg/debug/dwarf2/pr80234-1.C: New test. * g++.dg/debug/dwarf2/pr80234-2.C: New test.
