  In a sector of fixed topological charge, the chiral condensate has a
discontinuity given by the Banks-Casher formula also in the case of one-flavor
QCD. However, at fixed \theta-angle, the chiral condensate remains constant
when the quark mass crosses zero. To reconcile these contradictory
observations, we have evaluated the spectral density of one-flavor QCD at
\theta=0. For negative quark mass, it becomes a strongly oscillating function
with a period that scales as the inverse space-time volume and an amplitude
that increases exponentially with the space-time volume. As we have learned
from QCD at nonzero chemical potential, if this is the case, an alternative to
the Banks-Casher formula applies, and as we will demonstrate in this talk, for
one-flavor QCD this results in a continuous chiral condensate. A special role
is played by the topological zero modes which have to be taken into account
exactly in order to get a finite chiral condensate in the thermodynamic limit.
