Comment(by stephen.hocking at gmail.com):

 Managed to compile it with -g and disabling the no-frame-pointer stuff,
 back trace now looks like this -

 (gdb) bt

 If there's anything else I can do, please let me know. Granted the malloc
 arena corruption happened some time prior to this, but it's curious that a
 transcode without using a cutlist is fine. It's been a while since I poked
 C++ with anything other than a sharp stick
