Use the _same_ toolchain as you use now, but build the code for 68000.
Then run the code on 68000 machine or emulator for such and the program
will crash when it does odd address access.  Check with debugger where that
happened.

(Assumes the issue is reproducible on 68000 build.)

There are nowadays several Linux based mobile devices.  Programs that wake
up frequently will decrease the use-time (without charging the battery 
in-betwee) from days to less than a day, something that uses constantly
100%, reduces it to hours.
