Setup: * dvd+rw-tools_5.19.4.9.7-1, * '-t unstable dist-upgrade' debian/knoppix, * cd/dvd writer is "Vendor: HL-DT-ST Model: DVD+RW GCA-4040N Rev: 1.15"
With version 5.19 I notice that growisofs command, on my computer (compaq/hp presario 2519eu), hangs at the flushing data step when burning a dvd (I have not tried another media). The two previous versions did not show that behaviour. Output of hanging session (I am using and reusing the same dvd+rw for the tests):

Now I attach growisofs in gdb, get traceback only, and detach: growisofs resumes.
Here is the gdb session:

./.. In the other terminal, as said, growisofs resumed up to the following:
/dev/dvd: stopping de-icing /dev/dvd: writing lead-out
I attach/traceback/detach again:

and then growisofs goes to completion:
/dev/dvd: reloading tray jddportable# echo $? 0
I verified DVD content and it is okay!
Perhaps a side effect of an incompatible library running on a too uptodate system?
In the meantime I have the workaround (gdb attach/detach), but I prefer, and I did, rolledback to the previous version.
Thanks a lot for your help!
Cheers, JD.
