Found a typo (extra semicolon, if ( ... ) ; { ... } ), which causes the
conditional to not apply.

This could potentially lead to an infinite loop in case of failure during autoincrement computations.

This was only found by source inspection, there is no known test case. But it was apparently encountered by some support customer.

How to repeat:
Found by source inspection.

Suggested fix:
Will commit patch.
