Hi Magnus,
I see another problem if we are not lucky and an existing application
breakpoint is exactly at the
same address of the temporary breakpoint used by the algorithm.
As breakpoints are stored with respect to their address here is what happens:
> b) Add the temporary breakpoint used by the algorithm
> breakpoint_add(target, exit_point, exit_breakpoint_size, BKPT_HARD))
> in armv4_5_run_algorithm
Here we are not really adding a new breakpoint as the address is the same.
> e) Unset and Remove the temporary breakpoint
> breakpoint_remove(target, exit_point) called from armv4_5_run_algorithm
Here we are removing the (unlucky) application breakpoint.
> f) Enable all
> breakpoints
All but the one we have removed.

Yes, the backup/restore of the whole list should work
