When retained objects are assigned into a C array of greater than 1 dimension
in a longer lived scope, the objects a potential leak is reported. I have tried
this with a static global 2d array and an instance ivar. Attached test case
contains both flavors.

Note that the same error does not occur with a 1d array.
