I think this has already been fixed by Ralph this morning. I had observed the same issue but is now gone.

I see "idx" instead of "index" in the code above. index may be a pointer to the "index()" function in your standard library? Anyway, depth=0 and idx=0 is totally valid, especially when called from hwloc_get_root_obj(). Something bad happened to the topology object? Can you print the contents of topology and topology->nblevels and topology->levels ?
