[svn-r11961] Purpose:
Bug fix in collective IO code
Description:
When select none occurs in one process, fm->select_chunk hasn't been allocated the memory(not allocated until create_file_hyper); however, this needs to be checked; it was caught with cmpi at NCSA linux cluster.
Solution:
Relocate the place to allocate the memory space for fm->select_chunk.
Platforms tested:
cmpi at tungsten
mpich at heping
kind of minor and let daily test catch other errors.
Misc. update:
This won't fix the failure at mir.
