Entirely my fault since I now realize that I didn't say explicitly
that it's about a symbolic link in my original post. And thanks at
lot, H5Lget_info() looks exactly like what I was looking for!

As usual this happened within a larger program;-( I will try to
cobble something together that does the same (I hope I have the
version that exhibited the problem somewhere in my version sys-
