When compiled -m32 with -fgraphite-identity on x86_64-apple-darwin10, the
following three libstdc++ testcases fail there execution tests due to assertion
failures.
FAIL: 23_containers/deque/cons/1.cc execution test
FAIL: 23_containers/deque/modifiers/swap/2.cc execution test
FAIL: 23_containers/deque/modifiers/swap/3.cc execution test
FAIL: 23_containers/vector/modifiers/moveable.cc execution test
The assertions are (in order)...
./1.exe
Assertion failed: (__gnu_test::object_counter::count == 10), function test01,

line 40.

line 113.
Abort
compiling these testcases without -fgraphite-identity eliminates the execution
failures.
