Subject: [PATCH] rar: Fix double free with over 4 billion nodes (#2598)
If a system is capable of handling 4 billion nodes in memory, a double
free could occur because of an unsigned integer overflow leading to a
realloc call with size argument of 0. Eventually, the client will
release that memory again, triggering a double free.
