    Description

      The test case is essentially this (it is just a template):

      create table t1 (a int primary key, v vector(96), vector(v)) engine=InnoDB;
      		 
      # insert 1000 rows into t1
      		 
      create table t2 (a int primary key, v vector(96), vector(v)) engine=InnoDB;
      		 
      # insert 30000 rows into t1
      		 
       
      		 
      START TRANSACTION;
      		 
      INSERT INTO t1 (v) VALUES (<one value>);
      		 
      INSERT INTO t2 (v) SELECT v FROM t2 tb1 ORDER BY VEC_DISTANCE_EUCLIDEAN(tb1.v, VEC_FROMTEXT('<vector in text form>')) LIMIT 10;

      The second insert is the one that crashes.

      On an ASAN build, it fails every time for me. On a non-ASAN build, It only fails half the time and with various stack traces.

      The data is from a benchmark. I couldn't replace it with random data in a limited amount of attempts, nor to reduce it significantly, so I'll provide the remaining part as is. Quite possibly a very small test can be created instead.
