No idea.. We could sidestep lazy loading here by using
get_class_binding_direct instead of lookup_member in lambda_function,
but I don't know if if that would have unintended consequences.
FWIW the closure for which op() lookup triggers lazy loading is for a
non-generic lambda from an instantiated function template scope and
captures another closure object that captures a dependent function
parameter (_overwrite in libstdc++'s <format> line 1607). So I'd guess
the entity dependency graph is pretty complicated..
And it seems lazy loading from maybe_lazily_declare can be quite
recursive, I wonder if that's expected? I attached the full backtrace
that leads mangle_decl recursion, and there's about 15 recursive calls
to maybe_lazily_declare in this backtrace which seem to go through
check_local_shadow. Maybe we can reduce this somehow?
This is just a naive experiment, but interestingly only two modules
tests fail if we remove the call to lazy_load_pendings from
maybe_lazily_declare:
