There is no mention of TemplateMatch in the duckdb source code as far as I can tell, are you sure you're raising this in the right repository, perhaps an extension you're using on top of duckdb?

I imagine you have a stack trace of the crash that you're extrapolating this from?

I see, so TemplatedMatch is the name
Perhaps related to duckdb/duckdb#8979 then

[wdroste]

We upgraded to v1.1.1 and haven't seen this issue since, thank you for looking into it.
