This is a memory leak that is unavoidable in any program compiled with V. But the allocated memory is a static allocation. There isn't really a reason to free it. It's used whenever tos2 is called, which happens in many places according to the code. If you complain that this is a memory leak, then you should complain that any static allocation is a memory leak.
