This seems likely to be a bug in libcudf's ORC reader. Has that been confirmed and if so, is there a corresponding bug against libcudf?

I have only filed issues against our project so far. I have not had time to dig into any of them and confirm if there are cudf issues or not. @jlowe if that is something you want to do feel free to dig into it.

Is this still relevant? It seems we just had a fixed in rapidsai/cudf#11525 but there is still rapidsai/cudf#11691.

Edit: Found that the merged PR didn't fix this. It fixed orc reader but didn't fix orc writer.
