Indeed, unlike the reduced testcase, for the original one it triggers during
fold_non_dependent_expr_sfinae which means that processing_template_decl is 0
and thus type_dependent_expression_p check Dodji added returns false
immediately.

Related to PR48749, where processing_template_decl is 1, but
type_dependent_expression_p is still false, because the COMPONENT_REF has
non-dependent type, yet its operands are dependent (it was created using
build_min_non_dep).
