The recent BtIO rework has changed quite alot of bluez code during this
week so the code base is inevitably less stable than it used to be. We
will try to iron out any outstanding issues during the next few days.

Could you describe in more detail the steps you've taken to make
bluetoothd segfault? I have not been able to reproduce this with my own
tests (mainly testing HFP, A2DP and Serial functionalities).

Your backtraces also didn't seem to contain much useful info. What I
usually do is after a git clone/pull I compile with
./bootstrap-configure && make
and then I can use the src/.libs/bluetoothd binary for debuging (e.g.
with valgrind or gdb). The --enable-maintainer-mode switch that
bootstrap-configure uses makes the produced bluetoothd binary load the
modules from the source tree instead of their usual location
(/usr/lib/bluetooth) which helps make sure you're only running code from
the latest git.

Thanks Johan, for the information and your help on the irc channel,

I sent a few hours more on debugging and even while we thought we
found the issue:
http://git.kernel.org/?p=bluetooth/bluez.git;a=commit;h=8fb3fd137f3d108e373df9501915ee9ff6e23f83

The problem is still there and bluetoothd segfauls when i try to let
my bluetooth keyboard or mouse connect.

Cheers,

Jelle

This was actually a pretty stupid thing I should have noticed earlier.
The parameter list to bt_io_get should end in BT_IO_OPT_INVALID but it
was ending in NULL for this call. I also found two other places with
problematic parameters to bt_io_get. All occurences have been fixed in
git now.

Make BT_IO_OPT_INVALID be 0 in the enum, and you can use the GCC
sentinel feature. Otherwise, it would have to wait for:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28319

Cheers

Thanks for the tip! However, there's still the problem that gcc seems to
want this parameter be of type char* and with gcc 4 gives the warning
"warning: missing sentinel in function call" because it is not. The
following page has some info about it:
