Summary: Segfault on starting game (when adding text to
bottom of viewport of scrolling window?)
Project: Freeciv
Submitted by: jtn
Submitted on: Sat 30 Apr 2016 02:20:48 PM BST
Category: client-sdl2
Severity: 3 - Normal
Priority: 5 - Normal
Status: None
Assigned to: None
Originator Email:
Open/Closed: Open
Release: S2_6 r32524
Discussion Lock: Any
Operating System: GNU/Linux
Planned Release: 2.6.0, 3.0.0
_______________________________________________________
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?)
