flac dev - Dec 2006 - flac-1.1.3 fails to decode where flac-1.1.2 works

I'm attempting to decode part of a largefile flac whose seektable is
broken or missing and the file is shorter then it's supposed to be,
when I use 1.1.2 it decodes fine, when I use 1.1.3 it fails

flac --decode --skip=719:58.0 --until=1024:58.0 -o
\/home\/sbh\/work\/hs\/out.wav
\/mnt\/ss\/sdb\/Sound\/Recording\/2006\-11\-29\/in.flac

out.wav: ERROR seeking while skipping bytes
                                        state = FLAC__STREAM_DECODER_SEEK_ERROR

Is there a way I can 'fix' the seektable with flac-1.1.3? What's my
best option moving forward here?

Thanks!

Attempt to resend this, I don't think it made it last time. This is a
big problem for me, as I often need to use --skip and --until on
unfinished files, and while it's slow it does continue to work.
Thanks,

Use metaflac to fix the seektable.

I use metaflac --add-seekpoint=20x filename.flac

are you sure it's a problem with the seektable?  flac-1.1.3 has
a new seeking algorithm and yuo may have hit a bug with it.

does it happen on any large file?  if so, what is the size threshold?
if not, can you host an example for me to debug with?

It's definitely happening with largefiles, around 3-4GB. Also, like I
was saying I normally like to cut parts of the file before the file
has been 'completed' using the --skip and --until.
