Index: gcc/dwarf2out.c =================================================================== --- gcc/dwarf2out.c (revision 232717) +++ gcc/dwarf2out.c (working copy) @@ -22970,6 +22970,7 @@ is_naming_typedef_decl (const_tree decl) { if (decl == NULL_TREE || TREE_CODE (decl) != TYPE_DECL + || DECL_NAMELESS (decl) || !is_tagged_type (TREE_TYPE (decl)) || DECL_IS_BUILTIN (decl) || is_redundant_typedef (decl) this unfortunately doesn't fix the ICE for me because we don't stream DECL_NAMELESS it seems. If I fix that the fix above works. The lack of consistency between where free-lang-data forces a assembler name and the debug expectation is disturbing (I suppose with -fno-lto-odr-type-merging it would ICE all over the place)
