Please update documentation (status of 3.8.2016): 1) DSA_SIG_new.pod DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure. So now function only allocates signature. 2) ECDSA_SIG_new.pod ECDSA_SIG_new() allocates a new B<ECDSA_SIG> structure (note: this function also allocates the BIGNUMs) and initializes it. Same here, but please indicate that this is changed in 1.1. >> The issue is not only for ECDSA but also for DSA_SIG and RSA, DSA, DH >> keys where situation is similar. > Do you have some examples of how this affects other structures?

In deserialization process just updates allocated key material. It seemt to me now is more easy just to perform "const cast hack" instead to rewrite totally code.
