I can't tell if this is a new crash triggered by the same create/destroy event or the old crash. The same scenario triggers the crash (create/destroy test99.pd in a new canvas) but gdb reports something different. This is on today's build, Oneiric 32 bit. test99.pd was attached on this thread and is again attached to this email.
