Heya,
Got bluetoothd to crash.
Machine 1, bluez 4.37 from Fedora 11, running simple-agent with
KeyboardOnly as the capability, Belkin BT 2.1 dongle.
Machine 2, running bluez from git master, running gnome-bluetooth
master, same Belkin dongle.
Run bluetooth-wizard on Machine 2 and attempt pairing against Machine 1.
When the passkey prompt appears on Machine 1, enter some junk.
The pairing on Machine 2 will timeout, and bluetoothd crash.
Program terminated with signal 4, Illegal instruction.

And under valgrind:
vex amd64->IR: unhandled instruction bytes: 0x43 0x61 0x6E 0x63 0x65 0x6C
==26202== valgrind: Unrecognised instruction at address 0x13dfa8.
==26202== Your program just tried to execute an instruction that Valgrind
==26202== did not recognise. There are two possible reasons for this.
==26202== 1. Your program has a bug and erroneously jumped to a non-code
==26202== location. If you are running Memcheck and you just saw a
==26202== warning about a bad jump, it's probably your program's fault.
==26202== 2. The instruction is legitimate but Valgrind doesn't handle it,
==26202== i.e. it's Valgrind's fault. If you think this is the case or
==26202== you are not sure, please let us know and we'll try to fix it.
==26202== Either way, Valgrind will now raise a SIGILL signal which will
==26202== probably kill your program.
==26202==
