Foreign key generation problem with Designer/2000

[Quoted] Hello together,

I work on a great data model (> 70 entities) with designer/2000. While generating foreign keys with the database design wizard I get the following errors

ORA-00600: internal error code, arguments [12421],[],[],[],[],[],[],[]
ORA-06512: at "DESIGNER.CIOFOEREIGN_KEY_CONSTRAINT", line 172
ORA-06512: at line 188.

Can anyone help me solving the problem?

Greetings
Ralf Klamma
