Hi, I'm also having a problem of failed verifications.
I'm using flac 1.0.3 on Linux on a Duron 600 machine.
These problems have also occured with Windows XP on the
same machine and with different versions of flac. The
binary I'm currently using is the one in Debian package
The problem seems to occur only at compression levels 4
and above. It doesn't always happen on every attempt,
but when it does occur, it does so at the same sample
and with the same expected/got results. I had some
trouble trying to use the options to tune the
compression to find out which feature was causing the
errors. flac reported that at -3 it's options are "-P-
-b 4608 -l 6 -q 0 -r 3,3 -R 0" but when I tried
substituting this for the -3 in the command line I got
the error "ERROR: invalid option '-R'". When I tried
removing the -R I got the verify error at the same
sample as usual. I will attach test case wav files with
three of the 4608 sample blocks which are failing.
iits1792.wav fails much more frequently than the other two.
Absolute sample=392, frame=0, channel=0, sample=392,
expected -1504, got -1376
fails approximately once every 150 tries
Absolute sample=1792, frame=0, channel=0, sample=1792,
expected -3316, got -3284
fails approximately once every 3 tries
Absolute sample=2430, frame=0, channel=1, sample=2430,
expected -7, got -39
fails approximately once every 500 tries
I am monitoring this bug, please let me know if there's
any other information that would be helpful.
