[IMP-dev] AngleRestraint

Hi,

I'm having some (random) errors with the AngleRestraint function.

I get a Segmentation fault (core dumped) error when applying an AngleRestraint restraint like:

i = 0 while (i <= particles-3): p1 = ps.get_particle(i) p2 = ps.get_particle(i+2) p3 = ps.get_particle(i+3) ar = IMP.core.AngleRestraint(IMP.core.Harmonic(0, 1), p1, p2, p3) m.add_restraint(ar) i += 3

The error is not persistent, meaning that if I run the code severe times, the error disappear and the code ends normally.

Is there any specify reason for such an error?

Thanks! Davide
