Hi Ewan, Can you give me some instruction about how can I reproduce the issue on a Nexus 6? (If you can't gave the information out then the disassembly of the offending function and the fault address might gave me some hint as well)
A SIGBUS error looks a bit strange for me but my best guess is that we manage to install a 2 byte thumb breakpoint on the 2nd 2 byte of a 4 byte instruction what results in an incorrect instruction opcode and from that point strange things can happen.
