I don't think you are using 10.3, because that doesn't have any JIT output in its explain plans, like you show.
I also can't reproduce the issue. What git commit are you compiling? What llvm and clang versions are you using? What non-default settings are you using? Can you reproduce the issue if you set JIT to off?
Also, can you post the data, or post a query which can be used to generate data, which produces the issue?
