Description
While the testcases look somewhat similar to MDEV-28345, the unknown-crash is in a different location (sql/sql_analyse.cc), and is generated by ASAN as unknown-crash. Note that MDEV-28345 also has an unknown-crash however that one is in my_strtod_int (strings/dtoa.c). Also, this testcase does not crash regular (i.e. non-ASAN) opt/dbg builds.
