+Bug #26104 Bug on foreign key class constructor
+
+Check that ref_columns is initalized correctly in the constructor
+and semantic checks in mysql_prepare_table work.
+
+We do not need a storage engine that supports foreign keys
+for this test, as the checks are purely syntax-based, and the
+syntax is supported for all engines.

+foreign key fk_bug26104 (b,c) references t1(a));
+ERROR 42000: Incorrect foreign key definition for 'fk_bug26104': Key reference and table reference don't match
