The bt only shows a stack size of 27. No recursion. I modified the tsan code to
print out what's in the shadow stack when it's about to overflow. It looks most
of the addresses are:

__gnu_cxx::__normal_iterator<armor::Disk**, std::vector<Disk*,
std::allocator<Disk*> > >
std::__unguarded_partition_pivot<__gnu_cxx::__normal_iterator<Disk**,
std::vector<Disk*, std::allocator<Disk*> > >,
__gnu_cxx::__ops::_Iter_comp_iter<DiskCompare>
>(__gnu_cxx::__normal_iterator<Disk**, std::vector<Disk*, std::allocator<Disk*>

std::allocator<Disk*> > >, __gnu_cxx::__ops::_Iter_comp_iter<DiskCompare>)
