That's what is happening here... on my test system (opensolaris 24 GB  
of RAM), I get that:

927/1659 Testing itkLargeImageWriteReadTest1      Passed
928/1659 Testing itkLargeImageWriteReadTest2   ***Failed
929/1659 Testing itkLargeImageWriteReadTest3      Passed

The surprising result is the one for itkLargeImageWriteReadTest3 which  
is not failing. The test seems to not even see the right image size,  
and allocates only 1154 MB instead of the 9346 MB that it should (try  
to) allocate.

I guess we should rather receive an exception there...
