(MySQL 4.0.1-alpha-Max-log, your Linux binary)
The following works fine (just a slight variation of what is in the manual):
CREATE TABLE t1 (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
PRIMARY KEY (id)
) TYPE=InnoDB;
CREATE TABLE t2 (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
t1id INT UNSIGNED NOT NULL,
PRIMARY KEY (id),
KEY (t1id),
FOREIGN KEY (t1id) REFERENCES t1(id)
) TYPE=InnoDB;
The following, however, crashes MySQL:
CREATE TABLE t1 (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
PRIMARY KEY (id)
) TYPE=InnoDB;
CREATE TABLE t2 (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
t1id INT UNSIGNED NOT NULL,
PRIMARY KEY (id),
KEY (t1id),
FOREIGN KEY (t1id) REFERENCES t1(id)
) TYPE=InnoDB;
CREATE TABLE t3 (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
t2id INT UNSIGNED NOT NULL,
PRIMARY KEY (id),
KEY (t2id),
FOREIGN KEY (t2id) REFERENCES t2(id)
) TYPE=InnoDB;
The log file says:
InnoDB: foreign constraint creation failed;
InnoDB: internal error number 17
InnoDB: Assertion failure in thread 45067 in file dict0crea.c line 1241
InnoDB: We intentionally generate a memory trap.

mysqld got signal 11;
I can send you the stack trace if necessary.
