This is a pure function that's supposed to be called only for its return value, which is being discarded here.

That function has an assert internally that is firing when we transform a declrefexpr referencing a lambda.
This happens on a transform with an incomplete template argument list. Empty even, all template arguments being null.

I can double check for more details, but a transform pass without any actual transformation shouldn't produce errors.
