Comment (by jscholl):

 You are right, it is most likely the same root cause. But no, the foreign
 call is not unsafe as far as I understand (the default is safe, right?).
 Also if I change it to an explicit safe or unsafe call the behavior is
 unchanged, so this does not seem to be a factor in this case.
