Bug#635664: regression: bluetoothd segfaults when upgrading from 4.94-2 to 4.94-3

Package: bluez
Version: 4.94-3
Severity: important

Hi,

I was building a debian sid rootfs for my debian freerunner and noticed
that during boot, bluetooth was not starting but segfaulting.

root@om-gta02:~# /etc/init.d/bluetooth start
Starting bluetooth:Segmentation fault
root@om-gta02:~#

Investigating the issue, it became clear that the problem was in
bluetoothd:

root@om-gta02:~# /usr/sbin/bluetoothd
Segmentation fault
root@om-gta02:~#

I tried out a rootfs I created a month ago which was using bluez
4.94-2 and found out that the issue was not existing there. When I was
running apt-get upgrade and it updated to 4.94-3 the issue appeared
again.

So this must be a regression from 4.94-2 to 4.94-3.

I didnt investigate any further the real cause of the segfault. If you
would like me to, please tell me how to proceed.

cheers, josch

Hi,

Thanks for your report.

I checked on sid/amd64, I dont have problem.
If you can, please send log of GDB and config file of bluez.

The change from 4.94-2, bluez-alsa only corresponded to multi-arch.
If alsa is used in your environment, alsa might have to be examined.

Best regards,
Nobuhiro
