Bug Fix Description: There was a problem with having a lot of groups nested together. We could only handle 1024 characters at most, but, in a parallel program especially, it could occur that there were lots and lots of groups and would be more than 1024. Solution: I made the "objname" part of the obj_t structure a pointer instead of a fixed size. Added code to allocate/deallocate the memory we need for it. Had to fix how the "prefix" was being handled in the h5dump program. It was also set to only 1024 characters in length. I made it dynamic. Added a test case...Go me! Platforms tested: Linux, Solaris
