Yes the Arduino bootloader will [clear the .bss segment](https://github.com/arduino/ArduinoCore-samd/blob/master/bootloaders/zero/board_startup.c#L101).

I think this can be mitigated by placing the `.noinit` section at the end of the RAM, assuming no boot-loader will ever use all the memory (and a heap).
Or placing it after `.bss` and before the heap. I'll prepare a pull request.

I'll include your clock setup code in the next revision when I adapt the driver to the new Watchdog API.
