You can use addr2line tool that is in the arm toolchain, using the PC given by the backtrace logs. This can help you to find the exact line where the segmentation fault is so that you can debug further. You might need to rebuild libskia with -g option. It is odd that it only happens on some devices, my guess is that it is timing related. For more information look in:
