Details:

Tried the sdl2-client for the first time in a while. Got a segfault when
starting a spawned server.

From the segfault location and visually, I think it might happen when the text
in the chat window reaches the bottom and hence scrolling has to be enabled?
(Perhaps related to bug #24401?)
