This is based on top of #24615 so I can test it faster. I will rebase before r? anyway. |

I'm sorry for the disruption, I didn't know this was in the works. My patch was small, so it should be simple. |
|
I'm throwing the code out anyway. Shouldn't matter |

There was a problem hiding this comment.
could you add a test for *const str as *const U (or something similar)?

This should hopefully fix all cast-related ICEs once and for all. I managed to make diagnostics hate me and give me spurious "decoder error" - removing $build/tmp/extended-errors seems to fix it.
I think I didn't run tests properly - my second call to select_all_obligations_or_error has made 3 tests fail. However, this is just an error message change - integer fallback never worked with casts.

Fixed test failure |

Thanks @dotdash |
