test case:

CREATE TABLE t1 (
        f1 VARCHAR ( 128 ) ,
        f2 VARCHAR ( 32 ),
        PRIMARY KEY ( f2 ( 2 ) , f1 )
)
ENGINE=HEAP KEY_BLOCK_SIZE = 512;
INSERT IGNORE INTO t1 VALUES ( 'te' , 'm') , ( NULL , 'think' );
INSERT IGNORE INTO t1 VALUES ( 'te' , 'm') , ( NULL , 'think' );

Also repeatable with single-part primary keys. Seems like it is important for the key to be a prefix key.

Commited test case

Reproduced again. Laurynas,
please refer to /mnt/x25m/heap-blob-bin/mysql-test/var/log/master.err at r900

To reproduce run:

./runall.pl --basedir=/mnt/x25m/heap-blob-bin --grammar=conf/engines/heap/heap_ddl_multi.yy --mysqld=--max_heap_table_size=2Gb --threads=4 --queries=1000K --duration=3600 --validator=None --valgrind

Re-assigning to you as apparently it is not reproducible with the latest branches, please close or update/reassign as necessary.

[Valentine Gostev (longbow)]

Fix is ok.
