bug about the audio decode at file libavcodec/wma.c

[xmxkw@…]

latest i get the mplayer code from svn, and use MingW32 to compile it, but some thing strange. when i first time to compile it, it play the wmv and rmvb is ok, but latest compiled seems bad it can not play the wmv file(the same video file can play with first compiled) .

the error ouput is follow:
$ ./mplayer.exe -quiet -slave /e/20000000000000000000000000000001_.wmv
MPlayer UNKNOWN-4.3.0 (C) 2000-2009 MPlayer Team

Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders

till print the line "Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders", it exit and no any other info,just quit, when i trace the code , it tend to the func av_cold ff_wma_get_frame_len_bits in libavcodec/wma.c . when i add a log print to it like follow:
int av_cold ff_wma_get_frame_len_bits(int sample_rate, int version,

unsigned int decode_flags)

{

int frame_len_bits;

av_log(NULL, 0, "");

if (sample_rate <= 16000) {

frame_len_bits = 9;

it works ...

i doubt it should relate to the stack, but when i add ldflag --stack 8000000 on it, seems useless.
i don't know how to make it work if not amend the code.

attach the configure options follow:

./configure --prefix=/d/workdir/tmp/mplayer/binary \

the bug maybe the declare av_cold's problem , see ​http://gcc.gnu.org/ml/gcc-bugs/2008-03/msg01768.html

Not a known issue, nobody else complaining, gcc bug is closed -> I'll assume everything is working ok again.
