By this case i just learned how to recompile a package with debug symbols, 
install it and step, with gdb, into its exectution to see where the error 
occurs - no further ambitions into internals of unknown crypto-packages :)

Btw, it looks like i'm ending up using your fine libssh after trying GnuTLS 
and libssh2 in my current project. Is it possible to use libssh with 
asyncronous i/o ? I have a select loop whith my socket descriptors (one for
accepting new connections, the other established ones, and handling signals). 
This approach fits exactly my use case, no need to fork a process for every 
connection. 

I have functions ready to deal with single bytes comming over the established
connections and act accordingly (using GnuTLS at the moment), all works fine.

But it would be a great benefit to use the ssh like key management and 
known/unknown hosts handling, which libssh provides out of the box.

Some hints into libssh's function documentation should be sufficient.

Thanks in advance.
