+	PR libstdc++/118160
+	PR libstdc++/100249
+	* include/bits/ranges_algo.h (__is_permutation_fn): Avoid a
+	dangling reference by storing the result of the iterator
+	dereference and the result of the projection in two distinct
+	variables, in order to lifetime-extend each one.
+	Forward the projected value to the predicate.
+	* testsuite/25_algorithms/is_permutation/constrained.cc: Add a
+	test with a range returning prvalues. Test it in a constexpr
+	context, in order to rely on the compiler to catch UB.
