--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- This is nasty, all we have is a SAVE_EXPR that is evaluated both outside of the lambda and inside of it, so ideally we'd capture a temporary assigned that SAVE_EXPR and use it inside of the lambda. But no idea how to find out that the SAVE_EXPR actually is evaluated also outside of the lambda.
