I've got quite a bit of code I'm trying to differentiate through, so wouldn't be easy to make an MWE. I hope somehow the info in the error message is enough to diagnose my mistake. After a long time spent compiling I got this error: https://gist.github.com/SamuelBadr/3f886f19364d11a250d89561e4e8db19

In case it's relevant, this was preceded by some warnings:

Okay that's definitely an error that we'd need to try to reproduce to be able to fix.

If even not minimal can you share the code that triggers?

bump @SamuelBadr

[SamuelBadr]

Oh, I'm sorry but I can't share the code. I instead started minimizing it but something else got in the way. (Revising my thesis!)

I'll update here as soon as I'm able to.

@SamuelBadr without a reproducer I'm going to go ahead and close the issue. Please reopen if it still errs.
