ERROR 1114 Stored Procedure/Create Temporary Table

I am attempting to move to the MariaDB 10.2 line for my production application. Previously my upgrade to 10.2 was blocked by MDEV-14857. Now in 10.2.13 this issue has been resolved, however I am running into a new problem. I have a nightly job that runs in a stored procedure that fails in MariaDB 10.2.13. The error I am getting is below:

ERROR 1114 (HY000): The table '#sql-daf_13' is fulldone

I realize that this error is normally due to a configuration issue, however look at the end of the error string, it says "done" after full.

I have narrowed down the issue using the following reproduction steps:

1. I have uploaded a sql script to ftp.askmonty.org/private called brycejlowe-permtest.sql
2. Install MariaDB 10.2.13 and source in the file, it creates a schema called scratch and a table called permtest1 which has about 422,000 rows in it.
3. Execute the following statements against that table:

   CREATE TEMPORARY TABLE scratch.temptest1 LIKE scratch.permtest1;

   INSERT INTO scratch.temptest1 SELECT * FROM scratch.permtest1;

   CREATE TEMPORARY TABLE scratch.temptest2 SELECT * FROM scratch.temptest1;

   ALTER TABLE scratch.temptest2 ADD INDEX `part`(`Part_no`);

The result in MariaDB 10.2.8 through 10.2.12 is a temporary table scratch.temptest2 with an index called part. However the result in 10.2.13 is the error:

ERROR 1114 (HY000): The table '#sql-daf_13' is fulldone
