Daniel,
are you using a non-latin1 character set? Have you looked in the error log
mysql.err? What, if anything, did mysqld-max print when it crashed?
From the manual http://www.innodb.com/ibman.html#InnoDB_history:
...
MySQL/InnoDB-3.23.49, February 17, 2002
...
Fixed a bug: if one defined a non-latin1 character set as the default
character set, then definition of foreign key constraints could fail in an
assertion failure in dict0crea.c, reporting an internal error 17.
...
Please upgrade to 4.0.2.

Subject: Foreign key bug in InnoDB?
Hi,
I'm using MySQL-Max-4.0.1-alpha on WinNT4SP6 with InnoDB as default
table type.
I have a database creation script like this:
//Section A
CREATE TABLE AParents (
Id int unsigned not null auto_increment,
Parent int unsigned not null,
primary key (Id),
index Parent (Parent)
) TYPE = InnoDB;
CREATE TABLE AChildren (
Id int unsigned not null auto_increment,
Parent int unsigned not null,
primary key (Id),
index Parent (Parent),
foreign key (Parent) references AParents (Id)
) TYPE = InnoDB;
//Section B
CREATE TABLE BParents (
Id int unsigned not null auto_increment,
Parent int unsigned not null,
primary key (Id),
index Parent (Parent)
) TYPE = InnoDB;
CREATE TABLE BChildren (
Id varchar(13) not null default '',
Parent int unsigned not null,
primary key (Id),
index Parent (Parent),
foreign key (Parent) references BParents (Id)
) TYPE = InnoDB;
When I run the section A and B in any order, MySQL crashes and InnoDB
tablespaces go wrong and they cannot be repaired (as I restart MySQL).
The crash appears when I create the second table with a foreign key
constraint.
Do I do something wrong or this is a real bug in InnoDB?
Thx,
Dani
