Summary	0011763: Xdmf file with hyperslab itemtype crashes Paraview
Description	The attached file, which is supposed to cut a 2x2x2 cube out of a larger 3x3x3 cube, causes Paraview to crash. ("* glibc detected * ... realloc(): invalid next size: 0x0000000008e1a800 ***") To extract the subgrid [0,1]^3 from the larger [0,2]^3 grid, the start-stride-count in the first DataItem is set to 0 0 0 1 1 1 2 2 2 The same behavior occurs when trying to access the opposite corner [1,2]^3 (the one with values in the [8,15] range) using 1 1 1 1 1 1 2 2 2 instead. The crash can apparently be avoided using ranges whose count values are at least 3 (which should obviously be too large for the 2x2x2 target grid), and even grossly out-of-bound values such as 12 11 321 1 1 1 6 13 13 are accepted without complaints, and result in 1 2 0 3 4 0 0 0 i.e. a copy of the beginning of the source array.
Steps To Reproduce	Open Paraview, File->Open attached file "hyperslab_test.xmf", hit Apply.
Additional Information	I have also reported this prospective bug to Project Paraview because it is unclear on which side the problem is.
Tags	No tags attached.
