--- Comment #27 from Nathan Sidwell <nathan at gcc dot gnu.org> --- I think the symbols containing 'Ul' should demangle -- they're lambdas and I'd expect my patch to fix those. Some of the others certainly look suspicious. Did they come out of the compiler, or are they the result of fuzzing? IMHO it'd be better to change d_print_comp to take a pointer to non-constant demangle_component, rather than use casts in the function. (I realize current patch may just be a proof of concept.) It looks a good approach to me.
