Problem with I_CONSTR flag (VASP 5.2.11)

I have a unit cell with 174 atoms for which I am constraining the magnetic moments.

I use the flag as follows:

M_CONSTR=001 001 000 ...

giving three coordinates for all 174 atoms. However, this build will only recognize N=57 sets of coordinates and less.

Is there a length limit for this flag? If so, how to change it so that it will read all 3*174 coordinates?
