--- Comment #2 from Nathan Sidwell <nathan at gcc dot gnu.org> --- Created attachment 40625 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40625&action=edit Reduced testcase ./obj/x86_64/gcc/cc1plus -fconcepts -std=c++1z -g3 79264-dbg.ii It's very easy to turn this into a different seg fault somewhere in the gimplifier. Sadly my 67273 patch doesn't fix this one.
