• src/tasks.c, src/taskvariabledelete.c: If task variables are deleted from a different context (i.e., executing context != owner of the task variable. The owner meaning the task that registered the dtor in question) the argument passed to the task variable dtor must be tvar and not *ptr which yields the executing task's value of the task variable instead of the owner's.
