+# Bug 12902967: Creating self referencing fk on same index unhandled,
+# confusing error
+#
+# Creating a self referencing foreign key on the same
+# column/index is an unhandled exception, it should throw a sensible
+# error but instead implies that your data dictionary may now be out
+# of sync:
+
+--source include/have_innodb.inc
+--source include/not_embedded.inc
+
+call mtr.add_suppression("In ALTER TABLE .* has or is referenced in foreign key constraints which are not compatible with the new table definition.");
+
+let error_log= $MYSQLTEST_VARDIR/log/mysqld.1.err;
+--source include/restart_mysqld.inc
+
+create table t1 (f1 integer primary key) engine innodb;
+
+# The below statement should produce error message in error log.
+# This error message should mention problem with foreign keys
+# rather than with data dictionary.
+--replace_regex /'\.\/test\/#sql-alter-[0-9a-f_\-]*'/'#sql-alter'/
+--error ER_ERROR_ON_RENAME
+alter table t1 add constraint c1 foreign key (f1) references t1(f1);
+drop table t1;
