Description
The following test case sometimes causes valgrind warnings on a normal debug build (non-valgrind).
# Run via MTR with
# ./mtr t1 --mysqld=--innodb --mysqld=--default-storage-engine=InnoDB --mysqld=--innodb-file-format=Barracuda --mysqld=--innodb-file-per-table=1 --valgrind-mysqld
# I doubt that InnoDB parameters are anyhow important, but anyway that's how I ran it when it was happening
DROP DATABASE test;CREATE DATABASE test;USE test;
create temporary table t1(a int)SELECT 1 a;
HANDLER t1 OPEN;
handler t1 read next;
