--- Comment #16 from Jonathan Wakely <redi at gcc dot gnu.org> --- Yes, mt allocator has problems, that's why we stopped using it in 2005, but the zerotier code isn't even using mt allocator. Their problem is probably something different. That's the problem with writing ghost stories instead of bug reports: ghosts aren't real.
