That's good information. It seems like you have no explicit call to libssh2_init() at startup of your application, since you write that the crash happens when trying to *connect* to an SFTP server. I guess that you either have a call to libssh2_init() in a constructor related to SFTP, that's not so good, because the library should only be initialized a single time in a single thread for each process. I guess that OpenSSL was somehow already initialized, and the crash happens becuse OpenSSL does not support being initialized twice. If this is the case, please move or add the libssh2_init() call into your application startup, immediately on startup, before any user interaction. Then only call libssh2_session_init() in your SFTP constructor. Let me know how it goes. //Peter _______________________________________________ libssh2-devel https://cool.haxx.se/cgi-bin/mailman/listinfo/libssh2-devel
