It seems to mention shell.c line 262 which is:
shell_surface_set_output (self, get_default_output (self->server-
>compositor));
shell_surface_set_output is this:
static void
shell_surface_set_output(CWindowWayland *cw,
struct weston_output *output)
{
struct weston_surface *es =
weston_desktop_surface_get_surface(cw-
>desktop_surface);
/* get the default output, if the client set it as NULL
check whether the output is available */
if (output)
cw->output = output;
else if (es->output)
cw->output = es->output;
else
cw->output = get_default_output(es->compositor);
if (cw->output_destroy_listener.notify) {
wl_list_remove(&cw->output_destroy_listener.link);
cw->output_destroy_listener.notify = NULL;
}
if (!cw->output)
return;
cw->output_destroy_listener.notify = notify_output_destroy;
wl_signal_add(&cw->output->destroy_signal,
&cw->output_destroy_listener);
}
It mentions a call to wl_list_insert. Maybe it refers to the call to
wl_signal_add? What could need fixing there?
Also, there are lots of "Invalid writes of size 8", but a lot of them
don't seem to originate from functions in my program, but from the
Wayland libraries themselves. What is going on there?
