[svn-r10951] Purpose:
Bug fix
Description:
Hyperslab selections that had a selection offset and were applied to a
chunked dataset could get into an infinite loop or core dump if the same
selection was used multiple times, with different selection offsets.
Solution:
"Normalize" the selection with the selection offset, generate the
selections for the chunks overlapped and then "denormalize" the selection.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
