Doesn't appear to be an issue anymore. I was able to get the version buffer overflow error in the latest code on develop branch (1.4)

Build tested: 1.4.1-1

I tested the latest build from buildbot today and the issue still exist.

I cannot reproduce. I believe I found a possible reason why i cannot reproduce and why you continue to see the issue.

Looking at the ticket description, it appears you were using mariadb-columnstore-server develop branch (commit 67452bc is in mariadb-columnstore-server). You should be using mariadb/server 10.4 branch.

Please let me know if this is the case, and if it is, please test using mariadb/server 10.4 branch and mariadb-columnstore-engine develop branch

Build verified: 1.4.1-1

The issue was discovered in 1.4.0-1 beta source code that I used to build the installation package. I don't know if ColumnStore was migrated to use the server code directly yet at that time. My last test was using 1.4.1-1 package from buildbot so the correct branch should have been used to produce the package, and that package still has the reported issue. I tested the latest packages from buildbot today and it is working correctly now.
