Nicer ICE for #67981 Provides a slightly nicer ICE for #67981, documenting the problem. A proper fix will be necessary before `#![feature(unsized_fn_params)]` can be stabilized. The problem is that the design of the `"rust-call"` ABI is fundamentally not compatible with `unsized_fn_params`. `"rust-call"` functions need to collect their arguments into a tuple, but if the arguments are not `Sized`, said tuple is potentially not even a valid type—and if it is, it requires `alloca` to create. ``@rustbot`` label +A-abi +A-codegen +F-unboxed_closures +F-unsized_fn_params |
