Mike Beckerle created DAFFODIL-2628:
---------------------------------------
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)
