[svn-r14973] Purpose: Fix bug in H5G_get_name_by_addr where buffer size is less than size of name
Description:
In the new tests merged from the fortran_1_8 branch, there is a test that fetches a dataset name in a small buffer. The call to H5G_get_name_by_addr wrote an extra byte off the end of the buffer. A simple and sufficient fix is to decrease the buffer size passed to strncmp by 1. This bug was only caught by Visual Studio 2005 with extra debug checks on.
Tested:
VS2005 on WinXP
