What kind of "start" command are you talking about?

If you put commands in ~/.gdbinit, they will be executed as soon as
gdb starts.

I seldom debug C++ programs, so I don't recall looking for this.

It is possible to create new buttons in DDD with user-defined commands.

This may be a defect or restriction in DDD.

You can tell whether some unexpected behavior is in DDD or GDB by
entering the equivalent command in the command window.

I'd have to create a test case to be sure, but I believe that GDB only
records the source location for a breakpoint, not each PC which is
affected.
