cpp panic when comparing struct with it's subtype

A compiler panic when comparing a struct with another that it's using as a subtype.

CODE

Outer :: struct {
    using inner: struct {a: int},
    b: int,
}

outer: Outer
if outer == outer.inner {
    //  (ノ ゜Д゜)ノ ︵ ┻━┻
}

OUTPUT

$ odin run .
bug.main
lb_emit_conv: src -> dst
Not Identical struct {a: int} != Outer
Not Identical struct {a: int} != struct {inner: struct {a: int}, b: int}
Not Identical 7460decd7a30 != 7460decd78a0
Not Identical 7460decd7a30 != 7460decd7930
src/llvm_backend_expr.cpp(2324): Panic: Invalid type conversion: 'struct {a: int}' to 'Outer' for procedure 'bug.main'
