[openssl-users] AES-GCM failing from Command Line Interface

I am trying to encrypt a short message using AES-256-GCM as mentioned in the subject.
My command is:
openssl enc -aes-256-gcm -p -in payload.txt -out enc.txt
I get prompted for password as expected.
The encryption goes well, and then I proceed to decrypt using:
openssl enc -d -aes-256-gcm -p -in enc.txt -out dec.txt
The program executes but I get a "bad decrypt" message. However, when I open dec.txt, it is the same as the original file payload.txt
My guess is that the problem is in the padding, but I have not been able to eliminate the error message, even setting the -nopad option and padding manually.
Can someone please explain to me why this might be happening?
I am running openSSL 1.0.1f (6 Jan 14) on an Ubuntu 14.04 LTS VM with current patches.
Thanks in advance for your help.
