[PD-dev] bug: loadbanged $1 not passed to outlet

[flo at mur.at]

Hi,

I stumbled across a bug today in an abstraction where a loadbanged $1  
is passed on to an outlet. The message can be picked up at the outlet  
as expected the first time the patch is loaded, but not when it is  
reloaded (for example because its creation arguments are changed in  
the parent patch calling it).

Attached is a minimal working example (abstraction plus calling  
patch). Open mmw_call.pd and follow the instructions there to get the  
idea.

Best,
flo.H
