This is the bug.
uint8_t ipad[16];
for (i = 0; i < keylen; i++)
ipad[i] = var1 ^ key[i];
The pbkdf kernel doesn't handle password lenghts > 16. I have
committed a fix by limiting PLAINTEXT_LENGTH. Arch Linux didn't
complain about stack smashing. Seems its gcc was built with that
feature turned off :-(

Do git pull and try again.

I will integrate keychain2john into john soon. I was under assumption
that I had done it until this mail came up.
