When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue.(CVE-2023-48706)");
