The problem was originally reported in https://github.com/bitcoin/bitcoin/issues/22450#issuecomment-880629375. This is a dedicated issue to track it independently because it is a different problem than the one reported in #22450 OP/description.

```
fuzz: addrman.cpp:149: void CAddrMan::SwapRandom(unsigned int, unsigned int): Assertion `nRndPos1 < vRandom.size() && nRndPos2 < vRandom.size()' failed.
