Description
I tried this code on nightly:
fn main() {
let mut result = vec![1];
let mut vector = Vec::new();
vector.sort();
result.push(vector);
}I expected to see this happen: compiler does not panic.
Instead, this happened: compiler panics and suggests I open a bug report.
I initially posted to #107087, but @compiler-errors says this is a different issue, despite panicking on the same line in snapshot_vec.rs. (Though I'm realizing now that might be the proximal cause but not very related to the root cause.)
