I've noticed that in GUI objects, its quite common to call the
canvas_* functions using glist_getcanvas(). I also just found out
that this causes a crash in [envgen] when this is done for
canvas_deletelinesfor(). See bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=2842897&group_id=55736&atid=478070
So it seems to me that glist_getcanvas() should not be called on the
glist before sending it to one of these canvas functions. I was
wondering if this is kind of a blanket rule, and we should be removing
the glist_getcanvas() calls in GUI objects. For example:
unauthorized/cooled~/cooled~.c:
canvas_deletelinesfor( glist_getcanvas(glist), (t_text *)z);
unauthorized/cooled~/cooled~.c:
canvas_fixlinesfor( glist_getcanvas( x->x_glist ), (t_text*)x );
In ggee/gui/w_envgen.h, I fixed the crasher by replacing:
canvas_deletelinesfor(glist_getcanvas(glist), x);
with this:
canvas_deletelinesfor(glist, x);
