I'm sorry to sound so "pedantic" but we have faced this same issue in
the past (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=19976#c7) and
the solution was to delay folding
(https://gcc.gnu.org/ml/gcc-patches/2008-10/msg01061.html).
And it's still the answer to many issues. There's an effort to delay folding of various things in the C++ front-end and once done, that effort may be extended to other things.
