My guess is that something changed between those version.

Either LAST_INSERT_ID() changed or how foreign keys are managed. In
either case, you'll find better information on MySQL list or release
It could also be something not directly linked to the message like

HI Toby:

Yes - the exact same SQL script is used to set up both databases (and
yes - InnoDB).

Same SQL script to set up the databases and tables (and created from
scratch each time). Same Java code unit tests - the only difference is
Debian (5.0.32) as opposed to Windows/Mac (5.0.45).

Weird, huh?!

Are they all using the same storage engine (differing defaults)?  
InnoDB checks such constraints, other engines generally do not.
