Yes, that's what I've thought about. I just don't really know how to set it up to trigger the issue and what to test. The questions I have about creating a test for this includes.

- how to setup something so that the same pipeline is used to generate multiple outputs
- what kind of/how to generate inputs will cause the streamer to switch between multiple sections
- how/what to test the output (the segfault would be easy to observe on ARM but the AArch64 version is likely just generating some wrong info)
