Accessing tuple-struct members fails in GDB

I tried this code:

Temporary breakpoint 1, main () at test.rs:26
26          let a = Foo::<i32>::new::<f32>(123, 456f32);
(gdb) n
27          let b = Foo::new::<f32>(123, 456f32);
(gdb) p a
$1 = {0: 123}
(gdb) p a.0
Anonymous field access is only allowed on tuples, tuple structs, and tuple-like enum variants

I expected to see this happen: gdb prints 123

Instead, this happened: "Anonymous field access is only allowed on tuples, tuple structs, and tuple-like enum variants"

• What version of Rust GCC were you using, git sha if possible. 257bf55827474e500d83d96b7a8f8ebacbd11e7d

Reproduce the failure using the Rust snippet in test.rs and GDB, starting with the tuple-struct expression at test.rs:26 and the p a.0 command. Trace how gccrs exposes tuple-struct members to GDB; done means GDB prints 123 for a.0 instead of rejecting anonymous field access.
