Forgot to include pd-list... ---------- Forwarded message ---------- From: "Ivica Bukvic" <[email protected]> Date: May 19, 2014 2:57 PM Subject: Re: [PD] [expr] external crashing pd To: "IOhannes m zmoelnig" <[email protected]> Cc:
This had been fixed in pd-l2ork a while ago, it is alloc/dealloc error where math is off by one and hence the crash. On top of that pd-l2ork version warns user they have exceeded the number of allowable arguments and fails to create the object this preventing potential problems that may come as a result of improperly instantiated object receiving data. Please dig through recent pd-l2ork commits to find the fix.
