---------------------------------------

             Summary: abort: invariant broken when assert test expression does not return boolean
                 Key: DAFFODIL-2628
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2628
             Project: Daffodil
          Issue Type: Bug
          Components: Back End, Middle "End"
    Affects Versions: 3.2.1
            Reporter: Mike Beckerle



Debugging a schema I created this little thing to print out a length I wanted to see:
```
        <dfdl:assert test='{ dfdlx:trace(dfdl:valueLength(message, "bytes"),"contentLen")  }'/>
 
```
Notice the mistake. I forgot to compare the value to 0 in the test. 
That expression returns an integer.

If you fix the expression (add " ge 0") then everything works fine.

But with the mistake you get an abort at runtime:
```
trace contentLen:DataValue(true)
