--- Comment #4 from ctice at gcc dot gnu.org --- Created attachment 36082 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36082&action=edit Tentative patch to fix this issue. I believe the attached patch will fix this problem. I would appreciate it if Eric would confirm that. ChangeLogs: gcc/cp/ChangeLog: * mangle.c : Add vtable-verify.h to include files. (get_mangled_vtable_map_var_name): If the DECL_ASSEMBLER_NAME is "<anon>" get the real mangled name for the class instead, and also store the real mangled name in a vector for use later. gcc/ChangeLog: * vtable-verify.c (vtbl_mangled_name_types, vtbl_mangled_name_ids): New global variables. (vtbl_find_mangled_name): New function. (vtbl_register_mangled_name): New function. (vtbl_map_get_node): If DECL_ASSEMBLER_NAME is "<anon>", look up mangled name in mangled name vectors. (find_or_create_vtbl_map_node): Ditto. (var_is_used_for_virtual_call_p): Add recursion_depth parameter; update recursion_depth on function entry; pass it to every recursive call; automatically exit if depth > 25 (give up looking at that point). (verify_bb_vtables): Initialize recursion_depth and pass it to var_is_used_for_virtual_call_p. * vtable-verify.h (vtbl_mangbled_name_types, vtbl_mangled_name_ids): New global variable decls. (vtbl_register_mangled_name): New extern function decl. libvtv/ChangeLog: * Makefile.am: Update to match latest tree. * Makefile.in: Regenerate. * testsuite/lib/libvtv: Brought up to date. * vtv_malloc.cc (VTV_DEBUG): Update function call to match renamed function (old bug!). * vtv_rts.cc (debug_functions, debug_init, debug_verify_vtable): Update initializations to work correctly with VTV_DEBUG defined.
