User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0
Build Identifier:

In the reproducer shell script attached below we have a FUNCTION histo which accesses a MERGE TABLE containing a part that is a REMOTE TABLE.

If the part is not remote (second last line of the script), it returns the correct result, a single value which happens to be NULL.

If the part is remote (last line of the script), we get an error: Function 'calc.int' not defined.

Reproducible: Always

Steps to Reproduce:

Run the attached demo.sh with pre.sql, master.sql, slave.sql and post.sql present. This script kills ALL running mserver5's and starts its own mservers on ports 5501 and 5502.

Actual Results:

Function 'calc.int' not defined

Expected Results:

+------+
| L2 |
+======+
| null |
+------+
