Let $X$ be a smooth curve defined over a field and $F$ a coherent sheaf on $X$.
I would like to show that $F/F_{t}$ is locally free, for $F_{t}$ the torsion subsheaf of $F$.
Since $F$ is coherent it is enough to show the stalk $F_{p}$ is free as an $(\mathcal O_{X})_{p}$-module for all $p$. How do I see that a torsion-free module is free in general in this case?
