With current OpenSSL master, the krb5 PKINIT tests are getting an
assertion failure which I can't attribute to our code (stack trace at
the end). It appears that EVP_EncryptUpdate() now insists on
non-overlapping regions, but bio_enc.c:enc_read() relies on being able
to decrypt an overlapping region.
The calling code is:
i = BIO_read(tmpmem, buf, sizeof(buf));
where buf is a local array of size 4096 which is not used for any other
purpose (i.e. has nothing to do with the tmpmem bio).
Program received signal SIGABRT, Aborted.
