src/pubkey.cpp
325 ↗	(On Diff #8452)	This part here is supposed to be: if (!ecdsa_signature_parse_der_lax(secp256k1_context_verify, &sig, vchSig.data(), vchSig.size())) { However, this causes a compiler error stating `.data()` is not a member function. I'm not sure how to rectify this.

src/pubkey.cpp
325 ↗	(On Diff #8452)	There does not appear to be an equivalent .data() function in boost::sliced_range (at least that I could find). As such, this will have to stay unchanged.

src/pubkey.cpp
325 ↗	(On Diff #8452)	sliced_range doesn't appear anywhere in Core and is an ABC thing from D1572 :/

src/pubkey.cpp
325 ↗	(On Diff #8452)	What about `&vchSig.front()` ?

Previously mentioned issue was resolved with Fabien's suggestion of using .front().
