The following code
struct C {
C(nullptr_t) = delete;
};
results in the compile error
<source>:2:7: error: field has incomplete type 'C'
2 | C(nullptr_t) = delete;
| ^
<source>:1:8: note: definition of 'C' is not complete until the closing '}'
1 | struct C {
| ^
Expected behavior is that the construction from nullptr_t is marked as a deleted function, so users get clearer error messages. Tested on LLVM/Clang trunk as per 20-08-2025 on Godbolt:

Changing the function to `C(decltype(nullptr)) = delete;` works as a workaround.
