Comment (by jrummell):

 As I read the Vorbis spec, the sample_rate specified in the test file is
 4261460864 Hz (as it's unsigned 32 bits). The conversion to int results in
 -33506432 Hz. vorbis_parse_id_hdr() doesn't report an error with the
 header, so it appears valid. Looks like ffmpeg.c later complains about the
 negative sample_rate.

 As this file was generated by a fuzzer, I don't know if there are any
 valid Vorbis files with sample_rate > 2147483647 Hz.
