--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
-fchecking=2 enables the call to fold_non_dependent_expr in
build_non_dependent_expr:
/* When checking, try to get a constant value for all non-dependent
expressions in order to expose bugs in *_dependent_expression_p
and constexpr. This can affect code generation, see PR70704, so
only do this for -fchecking=2. */
if (flag_checking > 1
&& cxx_dialect >= cxx11
/* Don't do this during nsdmi parsing as it can lead to
unexpected recursive instantiations. */
&& !parsing_nsdmi ()
/* Don't do this during concept processing either and for
the same reason. */
&& !processing_constraint_expression_p ())
fold_non_dependent_expr (expr);
