These are not problems, the messages are caused by gdb trying to read
across the end of the address space, probably while backtracing through the
stack frames. Ignore the messages.
The more rare is:I can use break's, step, and more. But sometime, when

Use the gdb command 'compare-sections' to verify the image loaded in gdb
against the image loaded on the target. If it matches, and what you see is
the current position in the source jumping around apparently random (but
with some form of progress) when you single-step, it's normal behaviour
when debugging optimized code. Turn off optimization and see if it helps.
