I'm still seeing this exact same crash with bash_4.3-7ubuntu1. In fact, I also see it with a bash binary built from the upstream git (bash 4.3 patch 18).
This is the stack trace I'm getting: codewiz@xyzzy:~$ malloc: unknown:0: assertion botched free: called with unallocated block argument last command: ll webserver/sffe/config/sffe_config.proto Aborting...
