I feel like something must be wrong with my build, but I did a clean rebuild and still get this

$ cargo +enzyme run --example rosenbrock_fwd_iter --release

Thanks for reporting, I was also wondering if it's just my local build, or if either I or Enzyme core broke it.

@wsmoses, were there any changes to Enzyme core since your last uograde? I also got this error now once I fused all commits (and updated Enzyme along the way).

No there shouldn't have been any
