bluetoothctl Segmentation Fault on confirm

bluetoothctl Segmentation Fault on confirm

[Jason Flanagan]

The issue that i'm currently having with BlueZ 5.29 is that when i say 
no to confirming a passkey i get a "Segmentation Fault". I've tried 
multiple times on multiple devices and i get the same result.

bluetoothctl
[bluetooth]#agent on
[bluetooth]#default-agent
[bluetooth]# pair XX:XX:XX:XX:XX:XX
Attempting to pair with XX:XX:XX:XX:XX:XX
[CHG] Device XX:XX:XX:XX:XX:XX Connected: yes
Request confirmation
[agent] Confirm passkey 080443 (yes/no): no
Segmentation fault

I'm not able to reproduce this. Could you try running bluetoothctl under 
valgrind or gdb and provide full backtrace of crash?

Sorry for the wait, I just heard back from my supervisor that the error 
only occurs when we cross compile with the uClibc library. 
(libuClibc-0.9.33.2)
The actual error message is

bluetoothctl[2545]: segfault at 0 ip b7564efd sp bff77324 error 4 in 
libuClibc-0.9.33.2.so[b753f000+4f000]

OK, I was able to reproduce this with musl C library.

PS please don't top post on ML

Patches that should fix the crash are on ML. Please test if that fix your 
problem.
