Stack allocation of EVP_MD_CTX structures is common, for example:
EVP_MD_CTX mctx;
EVP_MD_CTX_init(&mctx);

This will cause binary compatibility issues if the size of EVP_MD_CTX structure changes (this will only happen with a major release of OpenSSL).

Applications wishing to avoid this should use EVP_MD_CTX_create() instead:

EVP_MD_CTX *mctx;
mctx = EVP_MD_CTX_create();
