Hi,
I tried, and also could not get 0,
but this is due to the Schouten identity...
You can play with the Option Schouten of Contract (and also with
Rename->True).
But it is non-trivial.

It really is better to just calculate scalar quantities.

I do not think that there are any bugs in DiracReduce. It is fairly simple code and biggest problem might be renaming of dummy indices,
but I think that works fine.

Regards,

Rolf
