With the lack of activity in this PR, I'm starting to believe this was a case of a certificate being malformed or some other factor than this specific module and was solved by correcting that issue.
If we do decide to make this change, I would use the reverse logic and only allocate/copy/trim if bptr->data != NULL. I'm pretty sure that's what @yorkie was eluding to with https://github.com/Southern/node-x509/pull/39/files#r75600803.

Seems like the better option would be to not run the allocation or anything that deals with data unless bptr->data != NULL.

This pull request should resolve #37 by checking if a extension contains NULL data. When implemented, the extension is still given as output, but with an empty value (\0).
