In case it isn't obvious:

What is `real code' ?
The initialization of local variables, is it considered part of the
prologue or real code ?

For practical debugging purposes (especially C++), the line number
information (and thus the breakpoint) has to be put before the initialization
code for local variables, so that we can debug object initialization.
