Comment 2 Stuart D Gathman 2012-03-20 00:57:59 UTC 
As discovered in bug#802070, this happens on CDs with 99 tracks (typically audiobooks).
Comment 3 Adrian Reber 2012-03-20 13:58:53 UTC 
Thanks for the report. I contacted upstream to see if they know anything about it.
Comment 4 Stuart D Gathman 2012-03-21 02:07:06 UTC 
In cdtext.c cdtext_data_init(), i_track gets up to 103 before crashing, and there are only 99 tracks.  I tried adding "if (i_track > 99) break;" - but it still crashes.  Getting new backtrace.

Patch that fixes the symptom

This fixes the symptom, but why does the loop not terminate normally?  Is 99 a hard limit?
Comment 6 Honza Horak 2012-03-21 13:40:08 UTC 
*** Bug 802070 has been marked as a duplicate of this bug. ***
Comment 7 Stuart D Gathman 2012-03-21 19:10:45 UTC 
The specification doesn't seem to be open.  I'm guessing that

a) there is a hard limit of 99 tracks, and it was felt there was no need to terminate the 99th track.  My patch would actually be correct in this case.

b) cdtext_data_init needs to break the loop when reaching the end of the block rather than relying on termination.  This is a good idea anyway in case of malicious or broken data in the cdtext area.
Comment 8 Stuart D Gathman 2012-03-21 19:14:19 UTC 
Provided patch may be sufficient while waiting for upstream.
Comment 9 Adrian Reber 2012-03-22 16:58:47 UTC 
Thanks for the patch. I will apply it.

Following answer from upstream:


"""
Thanks for the report. I just had a chance to look at. Yes, this is a bug in current sources.
                                                    
Red Book standards limit the number of tracks to 99. See for example item
3 of http://en.wikipedia.org/wiki/Red_Book_(CD_standard)#Technical_details

I've recompiled the code to lower the track limit to 9 tracks and I get a
memory violation using valgrind in freeing memory similar to one of the 
reports. I will be changing the code along the lines of the patches I see 
in the reports but slightly differently to ensure this is covered more
pervasively and to warn when there is a violation.
