<p>pd 0.47-0 on gnu/linux debian jessie</p>
<p>steps to reproduce:</p>
<p>$ valgrind pd<br/>
create new patch<br/>
ctrl-1 to create new object box<br/>
type "bng"<br/>
click on the canvas to instantiate the object</p>
<p>now two errors are reported by valgrind</p>
<p>note: the error doesn't occur on additional bng objects, only the first<br/>
the error isn't triggered when creating a first bng with ctrl-shift-b</p>
<p>line 371 of g_bang.c is<br/>
if (action == LB_LOAD && x->x_gui.x_isa.x_loadinit)</p>
<p>so I guess something might be wrong with x_loadinit initialisation at pd startup?<br/>
not familiar with the gui code so that's just a guess</p>
<p>$ valgrind pd<br/>
