Annamalai Gurusami 27ecea534c Bug#13635833: MULTIPLE CRASHES IN FOREIGN KEY CODE WITH CONCURRENT DDL/DML ... There are two threads. In one thread, dml operation is going on involving cascaded update operation. In another thread, alter table add foreign key constraint is happening. Under these circumstances, it is possible for the dml thread to access a dict_foreign_t object that has been freed by the ddl thread. The debug sync test case provides the sequence of operations. Without fix, the test case will crash the server (because of newly added assert). With fix, the alter table stmt will return an error message. Backporting the fix from MySQL 5.5 to 5.1 rb:961 rb:947		2012-03-01 11:05:51 +05:30
