This was compiled from unmodified sources. According to hints found at BLFS, compile option -DWITH_EXTRA_CHARSETS=complex was used.
There seems to exist no further documentation on that option, but apparently that mode incorporates built-in latin1, latin2, etc., but not ascii (see mariadb-10.5.8/cmake/character_sets.cmake).
To reproduce the segfault, it is of course necessary that the specified or default of character-sets-dir does not exist, eg. like running the client from a different environment than compiled to.

I cannot repeat that, there is no crash for me, charset_info isn't NULL, because ascii is a compiled-in charset, so it does not need any character-sets-dir.
How did you compile?
