--- Comment #18 from Martin Liška <marxin at gcc dot gnu.org> --- Created attachment 42562 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42562&action=edit Reduce test-case I've got following test-case that started with r253608: $ ./xg++ -B. -std=c++1z -mavx512dq -c /tmp/repro.ii cc1plus: internal compiler error: Segmentation fault 0x1203f31 crash_signal ../../gcc/toplev.c:326 0x1575044 decl_assembler_name(tree_node*) ../../gcc/tree.c:672 0x92d913 hash_table<mangled_decl_hash, xcallocator>::find_slot_with_hash(tree_node* const&, unsigned int, insert_option) ../../gcc/hash-table.h:892 0x929e90 record_mangling(tree_node*, bool) ../../gcc/cp/decl2.c:4405 0x989780 mangle_decl(tree_node*) ../../gcc/cp/mangle.c:3842 0x1575094 decl_assembler_name(tree_node*) ../../gcc/tree.c:673 0xc7e3ed symtab_node::get_comdat_group_id() ../../gcc/cgraph.h:215 0xc96888 analyze_functions ../../gcc/cgraphunit.c:1081 0xc9bac3 symbol_table::finalize_compilation_unit() ../../gcc/cgraphunit.c:2666 $ ./xgcc -v Using built-in specs.
