Dear list, I found something that seems like a bug to me, but I’m still not sure, it could be something in my code. Could someone take a look and tell me if I’m doing something incorrectly?
The GUI object pasted below will sometimes crash on close when in a sub-patcher, but not in a top level patcher.
What is confusing to me is that the order of objects in the .pd file seems to make a difference.
On my system this patch crashes on close with a Segmentation Fault: 11:
here it doesn't crash, but gives me an "error: consistency check failed: drawline".
in any case, i think you should call `canvas_deletelinesfor()` unconditionally, even if the object is not visible. something like:
~~~ static void basicgui_delete(t_gobj *z, t_glist *glist) { printf("%s %p \n", __FUNCTION__, z);
t_canvas *canvas = glist_getcanvas(glist); t_basicgui *x = (t_basicgui *)z; t_object *ob = pd_checkobject(&x->ob.te_pd);
if(canvas->gl_editor) { sys_vgui(".x%lx.c delete %lxBOX \n", glist_getcanvas(glist), z ); } if(ob && glist_isvisible(glist)) { glist_eraseiofor(glist, ob, x->io_tag); } canvas_deletelinesfor(canvas, ob); } ~~~

PS: for the future, could you *attach* your files rather than paste them inline? it makes it so much easier to try them out.
