--- Comment #2 from John David Anglin <danglin at gcc dot gnu.org> ---
Looks as if the problem is here:

#else
// The C library doesn't provide any aligned allocation functions, declare
// aligned_alloc and get a link failure if aligned new is used.
extern "C" void *aligned_alloc(std::size_t, std::size_t);
#endif

Possibly, a better solution might be to provide an implementation that aborts.
