There is a double free error in ssh2john if you run it against a file
that contains two ssl certificate blocks.
Just take a random certificate, add it twice to a file:
cat test.crt test.crt > out.crt
Seems there is a loop that is freeing all openssl objects at the end of
the loop and then reusing the same objects and freeing them for every
iteration of the loop.
