Thanks, the log is helpful. This is likely an out-of-bounds access in that bluetooth library detected by -fsanitize=bounds.

Try the latest release (NMF26O.2016.12.12.04.03.44). It shouldn't crash anymore.

This bug will be kept open to track fixing the detected undefined access even though it should be successfully worked around now.

OTA update with latest, pairing is still failing.
Same issue with bluetooth share app is crashing.
Crashing happens with Jabra headset. Even though crash with bluetooth app, devices says headset is paired. When trying to play music through headset, it does not work.
Issue not happening with Marshmallow.
Logs attached.

Well, it's almost certainly the bounds sanitizer catching an out-of-bounds access, but it could be in any of the libraries statically linked into that one. I don't have any bluetooth devices to test with, so all I can do is take shots in the dark. I don't have room to keep around symbols for each build but I'll do it for the next set so I can translate those tracebacks into something useful.

Thank you for your help. This is not a show stopper anyways. Love the ROM. This is exactly what I was looking for. Donated 100 $ today. Thank you again for your time.

Thanks to reproducible builds this can probably actually be solved now:

[strcat@thinktank hw]$ addr2line -e bluetooth.default.so 000d5416
/proc/self/cwd/system/bt/stack/./sdp/sdp_api.c:361 (discriminator 1)

So it's really libbt-stack that needs the bounds exception, it just gets statically linked into the other library.

Please try the new NMF26Q.2016.12.17.07.29.30 release.

I can confirm bluetooth is now working, testing with Pebble+Gadgetbridge.
Thanks mate!
