[PD-dev] gui-object's "receive"-bug

[IOhannes m zmoelnig]

hi, i just noticed a bug when setting the "receive"-label of a 
gui-object via the [receive $1( message.
while the label get's updated in the properties-box, it does not unbind 
from the old label and does not bind to the new label.

this is because the old (iemgui-x_rcv) and new (rcv) labels are compared 
for equality (btw, wouldn't comparing the symbol-addresses be faster 
than string-comparing the character arrays ?) *after* they are set to 
the same value.

iemgui_receive() (line 378 of g_all_guis.c from the CVS (and 
pd-0.37..0.38test4)) reads:
     iemgui->x_rcv = rcv = canvas_realizedollar(iemgui->x_glist, rcv);

but shoud rather read:
     rcv = canvas_realizedollar(iemgui->x_glist, rcv);

("iemgui->x_rcv = rcv" will be set later anyhow)

and could the debugging lines 356-357 be left out ?
