That assertion failed because in the release function (moments after the assertion) we were indeed forgetting to mark the vma as cleared. The consequence was when testing an invalid relocation address, we would try to release the vma twice (following the couple of attempts to verify the address) and on the second release notice that the first release was incomplete.
