Description:
From either jdbc or mysql client, the mysqld (server) crashes when executing a multi-table delete.

This only happens on the linux version; the windows version works fine.

It produces the following SQLException:
SQLException: Communication link failure: java.io.EOFException, underlying cause: null

How to repeat:
DROP TABLE IF EXISTS sb_acls;
CREATE TABLE sb_acls(
aclId                   BIGINT NOT NULL PRIMARY KEY,
status                  TINYINT(1) NOT NULL
)TYPE = InnoDB;

DROP TABLE IF EXISTS sb_acl_notes;
CREATE TABLE sb_acl_notes(
refId                   BIGINT NOT NULL PRIMARY KEY,
aclId                   BIGINT,
INDEX                   idx_acl(aclId),
FOREIGN KEY (aclId) REFERENCES sb_acls(aclId) ON DELETE RESTRICT
)TYPE = InnoDB;

INSERT INTO sb_acl_notes VALUES(1,NULL);

DELETE sb_acl_notes, sb_acls FROM sb_acl_notes AS a LEFT JOIN sb_acls AS b ON (a.aclId=b.aclId)
WHERE a.refId='1';

with just-pulled 4.1-bk the following happens:

DELETE sb_acl_notes, sb_acls FROM sb_acl_notes AS a LEFT JOIN sb_acls AS b ON
(a.aclId=b.aclId)
WHERE a.refId='1';
ERROR 42S02: Unknown table 'sb_acl_notes' in MULTI DELETE
DELETE sb_acl_notes, sb_acls FROM sb_acl_notes  LEFT JOIN sb_acls ON
(sb_acl_notes.aclId=sb_acls.aclId)
WHERE sb_acl_notes.refId='1';
-- and here it crashes.

Still seems to happen in 4.1.7 under Windows Server 2003. We have an application crashing the mysqld-nt.exe process when invoking a certain feature. This is the last statement in the general log:

DELETE mww.BESTANDSKORREKTURANFORDERUNG, mww.BESTANDSKORREKTURANFORDERUNGPOSTEN FROM mww.BESTANDSKORREKTURANFORDERUNG left join mww.BESTANDSKORREKTURANFORDERUNGPOSTEN on (mww.BESTANDSKORREKTURANFORDERUNGPOSTEN.x_bestandskorrekturanforderung_nummer = mww.BESTANDSKORREKTURANFORDERUNG.nummer) WHERE ursprung != 3 and istVollstaendigBearbeitet = false

MySQL is running as a service on the machine.
The following information is written to the event log:
Faulting application mysqld-nt.exe, version 0.0.0.0, faulting module mysqld-nt.exe, version 0.0.0.0, fault address 0x0013205c.

I will upload the Windows crash dump.
