The function
'EVP_PKEY * d2i_PUBKEY(EVP_PKEY **a,unsigned char **pp, long length)'
modifies the pointer *pp ( *pp += length ).

It's not a bug (I guess it simplifies programming)

save the pointer, i.e. :
unsigned char *buffer; // points to the binary SubjectPublicKeyInfo
// structure
long len; // the length of the buffer
....
unsigned char *p = buffer;
EVP_PKEY *key = d2i_PUBKEY(NULL, &p, len);
