The functions MY_CHARSET_HANDLER::caseup() and MY_CHARSET_HANDLER::casedn() in their virtual imlementations do "const char *end= src + srclen" in the very beginning. Therefore src cannot be NULL to avoid "UBSAN: SUMMARY: UndefinedBehaviorSanitizer: nullptr-with-offset". Adding DBUG_ASSERT(src != NULL) into all virtual implementations, to catch this problem in regular Debug builds (without UBSAN). Fixing Master_info_index::get_master_info() to check connection_name->str. If it is NULL then passing empty_clex_str into IdentBufferCasedn instead of *connection_name.
