commit 20b82b514d81a64f5b240788e5051167456af379 on dec 20th creates an
issue where NULL can be passed to EVP_MD_CTX_destroy
Specifically d1_both.c:221
EVP_MD_CTX_destroy(frag->msg_header.saved_retransmit_state.write_hash);
Doing a DTLS negotiation between FreeSWITCH and Google Chrome using WebRTC
a segfault results every time.
adding a NULL check such as this resolves the issue but may not be the
correct solution.
if (frag->msg_header.saved_retransmit_state.write_hash)
EVP_MD_CTX_destroy(frag->msg_header.saved_retransmit_state.write_hash);
This change has just gone into Debian Wheezy and is starting to affect
anyone using FreeSWITCH with Chrome WebRTC.
