Prima-facie , it appears not and we > will need an appropriate fix for the release branches. Given that the patch for PR87369 eliminates the ICE, it's probably preferable for backporting to a separate patch that is only used on the release branches. That patch has now been soaking on trunk for a while now, so is likely to be pretty safe. I am a bit worried however, that the patch papers over a likely trunk ICE that isn't really fixed. It would be nice to investigate further if some additional mitigation is warranted.
