I ran vanitygen and oclvanitygen on the same machine, and realized after my run that both exe's share the same output file.

I've had experience in the past where many programs append to the same TXT file that corruption might happen.

Regardless of the source of the corruption, what is the most complete way to validate a key created by vanitygen?

Update

I added the developer tag since I'm looking to do validation in bulk. Command line scripts also work.

If you don't want to do it online, you can try to import the private key into Bitcoin-Qt then see if the matching public key is the one you expected.

My best recommendation is to try and import the private key into https://blockchain.info/wallet/ service. This can be found under the advanced tab of the wallet. The corresponding public key will be added into your wallet for deposits.

A second option which does not require and account is to go via https://www.bitaddress.org and parse it with the vanity address tab.

The pycoin Python library could be a good starting point. It has a utility that will give you the public key for a given private key. Unfortunately it doesn't seem to have a command line interface suitable for easy programmatic use.
