Thanks for your bug report. What was the table definition for "E" before the crashing ALTER TABLE?
Indeed it's very similar to bug 951588. There is a difference though that 951588 testcase does not exercise auto_increment, and this crash is in the auto_increment code path. Extending the 951588 testcase to exercise auto_increment goes through this code path, but does not assert.
