Invalid debuginfo with enum variant named the same as a struct #41193
Description
I tried to debug wth lldb this code:
use std::collections::HashMap;
#[derive(Debug)]
enum En<'a> {
None,
Bar(&'a Bar<'a>),
}
#[derive(Debug)]
struct Bar<'a> {
next: En<'a>,
}
fn main() {
let mut all_objects = HashMap::new();
let bar: Bar = Bar {
next: En::None,
};
all_objects.insert(1, bar);
let b1 = all_objects.get(&1).unwrap();
println!("b1={:?}", b1); //line 22
println!("end");
}
When try to set breakpoint to line 22 and print b1:
$ lldb target/debug/test
(lldb) target create "target/debug/test"
Current executable set to 'target/debug/test' (x86_64).
(lldb) b 22
Breakpoint 1: 2 locations.
(lldb) r

19 };
20 all_objects.insert(1, bar);
21 let b1 = all_objects.get(&1).unwrap();
-> 22 println!("b1={:?}", b1); //line 22
23 println!("end");
24 }
(lldb) p b1
