Description

When dumping this disc with a Plextor PX-760A, aaru crashes while inspecting the disc's geometry. Notably, the message Disc contains a hidden track... appears in stdout immediately before the crash. Transferring the disc into a Plextor PX-716A, aaru does not print that message, instead it prints Checking mode for track 7.... The disc is multisession, so my guess is that there is some conflicting details in how the drive is reporting the multisession behavior back to aaru.

I re-dumped the disc with aaru v5.2, which succeeded in both the PX-716A and PX-760A drives and produced identical images; aaru image compare of the successful v5.2 (image 1) and v5.3 (image 2) disc images reports Sector 135442 has different sizes (2324 bytes in image 1, 2352 in image 2) but are otherwise identical for sectors 135442 through 135586.

I apologize for lacking some detail, but I thought it was important to log the bug even if I lacked the debug output, especially as I understand you may have a disc en route to you now.

Exact command line used

sudo aaru media dump /dev/sr0 1998.11.01-Björk-All.is.Full.of.Love-US-63723.2-075596372329.aaru

Expected behavior

Log produced by aaru v5.3 with Plextor PX-716A: 1998.11.01-Björk-All.is.Full.of.Love-US-63723.2-075596372329.log

Output of command execution with debug output enabled

I wasn't able to capture this output.  I was required to deliver the CD to the postal service just as I was investigating.
