If invalid data is sent repeatedly from a IRC server to a LeafDigital LeafChat IRC client, the program will stop responding. Restarting the application will be required in order to regain normal functionality. 

/* The MDMA Crew's Proof-of-concept code for the DoS affecting LeafChat
 *
 * When the LeafChat IRC client recieves invalid data from the server, it
 * displays a dialog box with an error message. Should the server rapidly
 * send invalid messages, the system soon becomes dangerously low in
 * resources and commits harikiri. :-)
