[VCDImager Bugs/Devel] Assertion failed reading Chinese VCD

[Nick Andrew]

G'day,

I'm using VCDImager 0.7.6. I used it to dump the Matrix VCDs I have
(some problem in the mpegs caused both of them to be truncated by
several minutes, but that's another story). Anyway I'm not sure
whether this is a bug or it's simply something that the imager
does not expect on the VCD:


--DEBUG: 48 1 14,     
!ASSERT: file vcd_image_fs.c: line 70 (_idr2statbuf): should not be reached

This is trying to read a Doraemon VCD with Chinese subtitles. Doraemon
is a Japanese cartoon, and the audio is Japanese, and chinese subtitles
have been added. I have 25 in this series (mass-produced, legitimate)
and I just popped in #07 to see what happens.

The code is obviously expecting an XA and not seeing it. I don't know
enough about the structure of VCDs to help in debugging. The ISO9660
filesystem mounts fine:

Is there any way I can help you to fix this bug?

Nick.
