The issue I need to add is to make gdb break at the beginning of the
construction of each (all) global object of the program.
Breaking at the beginning of the program does not solve this. Please
see my original with this clarification, so maybe I can be clearer.

One possible solution is: add breaks in the ctors of ALL types, run,
and at main delete all those breakpoints.
Another solution is to do some handling of each
__static_initialization_and_destruction_0 which varies depending on
the context.
