Code

The code should not compile, as there is a missing unwrap at the commented location. But instead of reporting an error, the compiler crashes.

The ICE occurs on stable and beta, however not on nightly (see version info below).
Adding the missing unwrap makes the code compile without ICE on stable, beta and nightly.

use compact_genome::implementation::DefaultSequenceStoreHandle;
use genome_graph::bigraph::implementation::node_bigraph_wrapper::NodeBigraphWrapper;
use genome_graph::bigraph::traitgraph::interface::{ImmutableGraphContainer, Edge};
use genome_graph::bigraph::interface::static_bigraph::StaticNodeCentricBigraph;

fn main() {
    let graph = genome_graph::bigraph::traitgraph::implementation::petgraph_impl::new::<DefaultSequenceStoreHandle, i32>();
    let mut bigraph = NodeBigraphWrapper::new_unmapped(graph);

    for edge_index in bigraph.edge_indices() {
        let mirror_edge_index = bigraph.mirror_edge_node_centric(edge_index); // adding .unwrap() here makes the ICE disappear
        let Edge {from_node: mirror_from_node, to_node: mirror_to_node} = bigraph.edge_endpoints(mirror_edge_index);
    }
}

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

Duplicate of #89686 and fixed by #89946. We generally track issues that are reproducible on master. I'm not sure if it's worth beta-backporting but going to close to clean-up. Thanks for reporting!
