+# Bug #18734396	INNODB IN-PLACE ALTER FAILURES BLOCK FUTURE ALTERS
+#
+# Temporary tablename will be unique. This makes sure that future
+# in-place ALTERs of the same table will not be blocked due to
+# temporary tablename.
+# Crash the server in ha_innobase::commit_inplace_alter_table()
+CREATE TABLE t1 (f1 INT NOT NULL, f2 INT NOT NULL) ENGINE=innodb;
+SET debug='d,innodb_alter_commit_crash_before_commit';
+Warnings:
+Warning	1287	'@@debug' is deprecated and will be removed in a future release. Please use '@@debug_dbug' instead
+# Write file to make mysql-test-run.pl expect crash
+# Execute the statement that causes the crash
+ALTER TABLE t1 ADD PRIMARY KEY (f2, f1);
+ERROR HY000: Lost connection to MySQL server during query
+# Startup the server after the crash
