Are there any (messy) workarounds for this? I have been refactoring a repo and
suddenly been getting this error too, but not for a templated bit. For me, it
is the constructor where the error points, with a different stacktrace to the
same `tree_check` function:

I am trying to make a reproducible example but I don't know exactly from the
refactor what is causing it. Might be completely different. Despite it coming
from `emit_mem_initializers`, on the two classes I get the error on, even I
remove all the class initializers in the constructor, still get the error. But
if you have a workaround I wonder if I may be able to adapt it to my issue.
