auto-reduced (treereduce-rust):

    A = {
        enum E {
            B,
        }
        0
    },

original:

// check-pass

enum E {
    A = {
        enum E { B }

Please submit a full bug report, with preprocessed source (by using -freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

Start with the reduced Rust reproducer in the issue and reproduce the ICE using the provided command. Inspect rust/typecheck/rust-hir-type-check-enumitem.cc around line 98 and the related enum-item stack frames, then verify that the example remains check-pass without an internal compiler error.
