Proposed resolution (approved by CWG 2024-02-02):

Change in 6.7.7 [class.temporary] paragraph 7 as follows:

The fourth context is when a temporary object other than a function parameter object is created in the for-range-initializer of a range-based for statement. If such a temporary object would otherwise be destroyed at the end of the for-range-initializer full-expression, the object persists for the lifetime of the reference initialized by the for-range-initializer.

[Accepted as a DR at the March, 2024 meeting.]

(From submission #490.)

Parameter objects are not temporary objects, according to 6.7.7 [class.temporary] paragraph 1. An exception hinting at this in 6.7.7 [class.temporary] paragraph 7 should be removed.
