Jira issue originally created by user @beberlei:

In a scenario where you want to diff the currenet schema against a slightly changed schema the following workflow is necessary:

$oldSchema = $sm->createSchema();
$newSchema = (clone)$oldSchema;
$newSchema->createTable(...);

$c = new Comparator();
$diff = $c->compare($oldSchema, $newSchema);
$diff->toSql($platform);

This only works if clone creates a deep copy of the schema.
