Segfault while writing Vorbis metadata

Description
I'm trying to transcode a FLAC file (I've attached a sample media) to Ogg Vorbis through libvorbis but FFmpeg will segfault leaving a null size .ogg file in the working directory.
It seems that it is unable to write the metadata section to the Ogg file. Stripping out all the Vorbis comments from the FLAC and trying again will result in a correct conversion.
I've attached a backtrace too, which includes the command I'm running and the configure options.
