Specifically we saw similar errors when the “type_traits” header gets included (either implicitly or explicitly) but were able to work around this in the 23.5 release." < https://developers.redhat.com/articles/2023/05/04/new-c-features-gcc-13#new_warnings> says: "GCC 13 implements many C2X proposals. These proposals align the C and C++ languages a little bit closer to each other by entwining certain features, and make programming in C easier and more secure." In the past I have often needed to install older GCC from source to work on legacy codes. If Fortran is not needed, the current clang compilers may be a good solution. -- George N. White III
