[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
