Comment (by dalecurtis):

 On closer examination one SSR conformance test fails with the SSR drop
 patch,
 http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_IEC_14496-4_2004_Conformance_Testing/audio_conformance
 /mpeg4audio-conformance/compressedMp4/as08_32.mp4

 [aac @ 0x1a8fac0] Input buffer exhausted before END element found

 as08_32 == core setup 8, sampling frequency 32

 It's failing for similar reasons to all my other SSR test cases,
 decode_spectrum_and_dequant() runs out of bits, but no idea if the root
 cause is the same.
