Josh Adams commented on DAFFODIL-2083:
--------------------------------------
I've created a pull request
(https://github.com/apache/incubator-daffodil/pull/212) that fixes the very
unhelpful Assert error message, but I think this test is broken anyway. I've
included an updated version that seems to work as intended, using dynamic
separators that don't clash with the separators specified in the record
sequence. It doesn't round trip though, as it doesn't add in the appropriate
escape chars (") on unparse around 'smith, jr.'
> abort in parser runtime - invariant failed with dynamic separator test
