Hi,

this error recovery ICE happens only with -Os and is just a P5 - on theother hand I would argue the reproducer isn't that exotic! - but seemsfixable easily and safely: cdtor_comdat_group immediately callsDECL_ASSEMBLER_NAME on both arguments and of course crashes if they arenull. Tested x86_64-linux.


Thanks, Paolo.
