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.
