New submission from Nga Chung <[EMAIL PROTECTED]>:
I am trying to transcode from an aac to a wma format. Valgrind reports
conditional jump or move depends on uninitialised value(s) in aac_sync()
(aac_parser.c:39).
I confirmed that this bug is reproducible in the latest subversion of FFmpeg,
SVN-r14172.
I uploaded the test file via ftp upload.mplayerhq.hu in the directory
/MPlayer/incoming/ngatestcase/uninit_condition_test.aac
My System Information:
OS: Linux Debian x32
kernel: Linux debian 2.6.18-6-486 #1 Fri Jun 6 21:47:01 UTC 2008 i686 GNU/Linux
gcc version 4.1.2 20061115
ld version 2.17
My Hardware Information:
32-bit Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz
Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 02)
To reproduce:
valgrind ./ffmpeg/ffmpeg_g -i uninit_condition_test.aac test.wma
The following is the output from Valgrind:
