Isn't it possible, that only removing this line should be enough? Calling flb_free on NULL should not be a problem.

There was a problem hiding this comment.
Just removing that line fixes the double free but considering that there are code paths that lead to calling free with block_id holding NULL it's worth adding the check since older systems (and maybe alternative libc implementations?) don't handle it gracefully.
