Compiler Unexpectedly Panicked, call function with wrong number of arguments #47706
Description
First of all, this only happens on nightly
rustc --version --verbose binary: rustc commit-hash: 97520ccb101609af63f29919bb0a39115269c89e commit-date: 2018-01-21 host: x86_64-unknown-linux-gnu release: 1.25.0-nightly LLVM version: 4.0 I tried to make the code as simple as possible, so it might look like something no sane person would write
pub struct Foo { foo: Option<i32>, } impl Foo { pub fn new(foo: Option<i32>, _: ()) -> Foo { Foo { foo } } pub fn map(self) -> Option<Foo> { self.foo.map(Foo::new) } }This is what i get as output
