--- Comment #16 from Jonathan Wakely <redi at gcc dot gnu.org> --- This is an old, latent g++ bug, but it now makes it impossible to use cuda with GCC (e.g. on Fedora) because of my libstdc++ changes. I will see if I can make another libstdc++ change to avoid the ICE without having to revert the change completely, as it was done to fix a non-conformance bug.
