Priority: 7 Private: No Submitted By: Hans-Christoph Steiner (eighthave) Assigned to: Miller Puckette (millerpuckette) Summary: make text_ypix() run only if visible, fixing GOP crashes
Initial Comment: So I am trying to track down some intermittent crashes related to GOP. The actual crash happens when hslider_draw_update() is called with a NULL glist as its second argument. Its intermittent and not easy to reproduce, but I have seen it about 20 times with the exact same stacktrace.
Here's the backtrace that I am getting: 0 pd 0x0001668f graph_graphrect + 15 (g_graph.c:619) 1 pd 0x00016a77 glist_ytopixels + 128 (g_graph.c:594) 2 pd 0x00016b71 text_ypix + 109 (g_graph.c:636) 3 pd 0x0004153e hslider_draw_update + 43 (g_hslider.c:40) 4 pd 0x00062769 sys_pollgui + 179 (s_inter.c:764) 5 pd 0x0005edd8 m_mainloop + 814 (m_sched.c:493) 6 pd 0x000618bf sys_main + 2909 (s_main.c:304) 7 pd 0x00002622 _start + 216 8 pd 0x00002549 start + 41
Since the crash here is related to hslider_draw_update() calling text_ypix(), and the rest of the GUI objects don't call text_ypix()/text_xpix() unless visible, I think its a good idea for hslider to do the same.
