When cloning a database from hot backups that for example has a db_block_size of 4k and the new init.ora has db_block_size of 8k you may get an ORA-600 [17585] when running a CREATE CONTROLFILE statement.

Call stack trace:

This can still occur even if you have the "*_IO_SLAVES" parameter commented out in the new init.ora as suggested in <Note 138621.1>.
