* This test is here to guard propagation of NaNs that happens on this image. NaNs are guarded |

* This test also reveals problems with uninitialized memory that happens only on this image. |
|
* This is very hard to hit and depends a lot on particular allocator. Run this test in valgrind and check |
|
