[openssl-users] Reg: [Crash inside SSL_CTX_free ()]

[Viktor Dukhovni]

You either have threading problems are sharing structures without
proper reference counting or other protections.  Perhaps the
X509_STORE used in the context was already freed by some other
caller?  Or something completely unrelated corrupted the heap.
The below is not sufficient for anyone else to help you, time
to get good at using a debugger, you probably want an SSL
library compiled with debugging symbols and not stripped.
