Comment (by vallenti):

 That's an interesting bug, which probably boils down to the following
 issue:
 {{{
 global s: set[T];
 for (i in s)
 {
     delete s[i];
     # ...
 }
 }}}
 Here, we delete the very element of the current iteration in the for loop.
 This probably invalidates C++ iterators and is causing the non-
 deterministic behavior.
