segfault remote table count: could not find L1.L1 NOT NULL as L1 L1.L1
Hi there,
when I run 'count' on remote table I get a segfault on worker server: 'could not find L1.L1 NOT NULL as L1 L1.L1 Segmentation fault'
Here is master(server/client) and worker (server/client), all are living on localhost (as it was shown in example https://www.monetdb.org/Documentation/Cookbooks/SQLrecipes/DistributedQueryP... ).

Thank you, Anton
Have you guys ever tested remote tables for the latest MonetDB v11.23.7 (Jun2016-SP1)?
On MacOS I have tested 'count' on remote table (as shown in my previous email) - it worked for MonetDB v11.21.17 (Jul2015-SP3) and did not for MonetDB v11.23.7 (Jun2016-SP1).

Thank you for reporting this problem. Your test case was now added to the nightly testing we have. Also I fixed the problem in the Jun2016 branch. So the next Service pack should include this fix.

Sounds good, thank you for your work!
