# Bug 11766634 59783: InnoDB data grows unexpectedly when inserting,
# truncating, inserting the same set of rows.
#
# Scenario:
# create table t1.  Insert $recs records.  check size of ibdata1.
# drop table t1.  create table t1.  Insert the same set of $recs
# records.  The size of ibdata1 must not increase.
