--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Also:
#define _GLIBCXX_DEBUG
#include <vector>
int main()
{
std::vector<bool> b;
std::hash<std::vector<bool>> h;
return h(b);
}
And a number of other debug mode failures related to access. I suspect FE
improvements to lookup have made some of our friend declarations stop working
as intended.
