<div style="">
<p dir="auto">It is strange. If compiled with clang and these options gnutls-cli` behaves differently when sending early data. The "new" behavior makes openssl s_server to quit and thus resumption which is what is tested by this test fails. When I compile with just clang-9 and not these flags it works. Could it be a bug of one of these sanitizers that we are seeing here?</p>
