From zlib manual (https://zlib.net/manual.htm):
"inflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if the end of the compressed data has been reached and all uncompressed output has been produced"
I was testing the Extended Clipboard implementation of LibVNCClient with UltraVNC server. Calling inflate() on stream sent by client results in Z_STREAM_END, which ultimately results in server crash.
