> that is indeed strange. You should be able to get a proper backtrace.

yes. I ran src/.libs/bluetoothd, it core dumped,
but I still cannot get a reasonable backtrace. Weird.

I'm not sure that that running src/.libs/bluetoothd is correct.
src/.libs/bluetoothd will use the libbluetooth.so.3 installed in
/usr/local/lib. If I want to use the library in the source area
(as I have not installed this version of bluez) I should run
src/bluetoothd. It does the library magic to use the libraries
in the src area.

I did this and it still core dumps and gdb still cannot read the
core. Time to go to bed.
