Hi Frank,
does this double-free error message only happen on quitting PD? This 
one i could reproduce and should be fixed now (i just synced the cvs).
The error Johannes reported seems to be different since it happens on 
destroying flext-based objects... i have no clue about that one.

best greetings,
