If I read your message right, it's a bug with when you want the result in a different tag? Will fix this soon, should be easy.
On your msg about mbzoltan, the fix is much appreciated, we'll definitely get that in the code base. Dont know yet about the option string, haven't looked at code yet.

Hi Tim,
I've found the bug in my code...
To get the sum of a tag on shared entities I need to call
pcomm->reduce_tags(gid_tag_vec, gid_tag_vec, MPI_SUM, sharedFaces);
and not
pcomm->reduce_tags(gid_tag_vec, gid_sum_tag_vec, MPI_SUM, sharedFaces);
Here is the new version, now it works...
