New Revision: 186396

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=186396
Log:
Fix PR52822 by explicitly checking for object identity before
move-assigning.  This is a simpler fix than was committed to 4.7 and
4.8.

	PR libstdc++/52822
	* include/bits/stl_algo.h (__stable_partition_adaptive): Avoid
	move-assigning an object to itself by explicitly testing for
	identity.
	* testsuite/25_algorithms/stable_partition/pr52822.cc: Test
	vectors, which have a destructive self-move-assignment.
	* testsuite/25_algorithms/stable_partition/moveable.cc (test02):
	Test with rvalstruct, which explicitly checks
	self-move-assignment.
