Take a look at the sources, hmac.h declares struct hmac_context: struct hmac_context { char ctx[HMAC_MAX_CONTEXT_SIZE]; char ctxo[HMAC_MAX_CONTEXT_SIZE]; const struct hash_method *hash; }; If compiled for a 32 bit virtual address space, this has an alignment requirement of 4 due to the hash pointer. In line 171 of auth-token.c, we have following declaration of ctx as a local variable in auth_token_get(): s...
