If you use the 'Change Settings' dialog box to reconfigure PuTTY's port forwardings while a session is running, more than once, and each time, add or remove a port forwarding in the remote-to-local direction, then PuTTY could crash with a memory access error, due to bad management of an internal linked list of requests of that type that it's waiting for replies to.
