Sorry for taking so long to reply. The original example I shared (https://gist.github.com/TimNN/501819422631149c3ab2b8cc0b15c98d) reproduces the issue for the AVR target. I'm not sure about the terminology here, but I would consider AVR "in-tree", even though it is still experimental. I don't know if / how the issue can be reproduced on other targets.
