Sure it does. For instance, by only reading the registry or a function
upvalue we may be able to access (and then call) some function that
otherwise could not be called at that point and (for instance) release some
resource that is still being used.

On the other hand, only because the example uses the debug library it does
not imply that the real bug is a direct consequence of that use. As this
bug involves the GC, it is worth investigating what is going on there.
