[svn-r11229] Purpose:
Big fix Description: A group opened by dereferencing a object reference would not work for H5Giterate(), due to the local heap & B-tree information not being cached. Solution: Get the local heap & B-tree info & point to that structure instead of the group entry for the group. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
