Something isn't working

Minimised this bug. Happens because of a stack-overflow or something similar due to a loop where >>> a=nk.hilbert.Spin(0.5, 4, total_sz=0)
>>> a.n_states
doing
b4 : True True False
getting hilbert index
- first time self.is_indexable = True, Spin(s=1/2, total_sz=0, N=4)
self._has_constraint = True
building bare self._constraint_fn = <function Spin.__init__.<locals>.constraints at 0x10cbcc160> and self._hilbert_index=<numba.experimental.jitclass.boxing.HilbertIndex object at 0x10c6d85b0>
doing
b4 : True True False
getting hilbert index
af : True True False

Came across this while discussing with Jannes.
This is a numba error because it core-dumps and disabling numba makes it work, but maybe we can find a workaround.
This works
This crashes with no info
