How suspicious is this backtrace if I'm messing around with Constr.Unsafe?

looks normal to me, you wrote a term with an unbound rel

Hm, I tried very hard to not invoke any operations that relied on having all the rels be bound. Is there a way to figure out what line of code (presumably Ltac2?) is invoking the problematic reduction(?)

view this post on Zulip Janno (Sep 23 2022 at 13:17):

I am not sure but whd_simpl_orelse_delta_but_fix reminds me of hnf. Are you using that? I don't think Ltac2 calls any reduction automatically anywhere so it would have to be in your code somewhere.

view this post on Zulip Janno (Sep 23 2022 at 13:22):

If you need reduction that is fine with unbound rels then I think the only option is the kernel's weak head reduction.

view this post on Zulip Jason Gross (Sep 23 2022 at 14:53):

I do call reduction with unbound rels, cbv beta and delta seem to work perfectly fine in most cases with unbound rels. I am calling hnf, but not on this term, I think. Does unification call hnf? This issue only happens when I leave an evar in the term (one that eventually gets unified with something boring like nat). I'm trying to minimize it, and have run into a bunch of other strange issues. Like when I define the terms this one depends on by transparent_abstract instead of Definition, I get an evar not declared anomaly (without even invoking Ltac2). And if I define them by tactics with transparent_abstract rather than giving the definitions explicitly with exact, then they all go through but instead of a not found anomaly, I get a different anomaly:

The evar not declared anomaly: https://github.com/coq/coq/issues/16534

view this post on Zulip Jason Gross (Sep 24 2022 at 10:24):

What about getting an assertion failure on

let normalize_evar evd ev =
  match EConstr.kind evd (mkEvar ev) with
  | Evar (evk,args) -> (evk,args)
  | _ -> assert false

Is this expected from messing with unbound rels?
