static inline int
armature_circle_doSelectJoint(void *userData)
{
  struct {
      void *vc;
      short select;
      int mval[2];
      float radius;
  } *data = userData;
  return (0 <= data->radius && data->select);
}
int
armature_circle_select(void)
{
  struct {
      void *vc;
      short select, mval[2];
      float radius;
  } data;
  return armature_circle_doSelectJoint(&data);
}

it's caused by the mismatch of the local struct declarations (might be a bug
in your app as well).
