I don't know much about type checking and @compiler-errors reviewed #122749, which apparently caused #127742, so: r? compiler-errors |

I'm not getting a great feeling from this approach. It seems like a very heavy hammer, and I'd first like to see a detailed analysis for why #127742 ICEs in the first place. |

I realized my solution is quite naive too, during solving the stack overflow bug. The nested types can get really deep to traversal. Anyway, a more detailed ICE analysis is added under the issue. |

A more correct approach might be adding a But then we would run into Perhaps I should close this as duplicated with #113125. |

Prevent types that contains error from passing typeck and causing error in const eval later.
Type visitor doesn't visit fields of ADT thus cannot detect error in them. So I created a custom visitor to allow recursive visiting.
Fixes #127742.
