Comment (by Mirraz):

 OK, you are right, condition is not "strange", it complies to
 specification which I found here:
 http://wiki.multimedia.cx/index.php?title=ATRAC3plus. My mistake.
 But this warning is not bogus, warning appears because compiler discards
 its suggestion about "ctx->num_quant_units" (1<=num_quant_units<=32) when
 "ctx" passed to "decode_quant_wordlen(gb, ctx, num_channels, avctx)" and
 anything can happen to fields of "ctx".
 Corrected patch was sent to ffmpeg-devel.
