OpenEnclave SDK Samples have Issues with Latest Intel SGX SW Updates

Hi,

There is an issue with running the OpenEnclave SDK 0.8.2 along with the latest Intel SGX SW updates released last night.

When the latest Intel SGX Linux 2.9.1 and Intel DCAP 1.6.100.2 are installed, and the remote_attestation sample and the attested_tls sample are built with clang, these samples segfault or fail. When built using gcc, the samples work fine.

We are trying to root cause and fix these issues. In the meantime, if you have an application built on OpenEnclave SDK, we recommend holding off on upgrading to the latest Intel SGX SW updates.
Thanks,
Radhika
