The problem appears to be here:
static void
digest_finish(PX_MD * h, uint8 *dst)
{
EVP_MD_CTX *ctx = (EVP_MD_CTX *) h->p.ptr;
const EVP_MD *md = EVP_MD_CTX_md(ctx);
EVP_DigestFinal(ctx, dst, NULL);
/*
* Some builds of 0.9.7x clear all of ctx in EVP_DigestFinal. Fix it by
* reinitializing ctx.
*/
EVP_DigestInit(ctx, md);
}
It looks like this results in a leak of the entire OpenSSL context for
each call to pg_crypt. Marko, I trust you've got a better solution for
this ...
