[Bug c++/115722] GCC uses old closure type when using as default argument instead of using new closure type each time

--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You missed this part:
The closure type is declared in the smallest block scope, class scope, or
namespace scope that contains the corresponding lambda-expression.

from expr.prim.lambda.closure/2

Which means the closure type is in the global scope here for this TU.
