[OpenSIPS-Devel] OpenSIPS Crash

[Bogdan-Andrei Iancu]

Thank you Ben :)

The backtraces report a double free, but the memops are performed via 
libcrypto ( opensips registers mem-specific functions to lib crypto).

Are you using in your opensips cfg any other module that might require 
ssl/crtypto, like tls_mgm, proto_wss ?
