--- Comment #5 from Tony E Lewis <TonyELewis at hotmail dot com> --- Thanks to all for all work on this. (Apologies if this isn't helpful but just in case it is...) I notice that the original Godbolt snippet ( https://godbolt.org/g/JnrZss ) has regressed from a rejects-valid in 8.1 to an ICE on trunk ("9.0.0 20180610") : g++: internal compiler error: Segmentation fault signal terminated program as Please submit a full bug report, with preprocessed source if appropriate. See <https://gcc.gnu.org/bugs/> for instructions. Compiler returned: 4
