I've discovered some mangling problems with lambdas. (a) divergence
from clang and (b) manglings that incorrectly demangle. With #a I'm not
yet sure who is correct. for #b g++ is definitely wrong.
From the docs, it doesn't appear to have been

odule streaming, could you please help me on this?
add it in to trees_{in,out}::core_bools. You could elide streaming for
non-FIELD_DECL decls.
Hope that helps.
