To add to that, if you also rely on those objects to be destructed
automatically (which the above fails to do), you need to use normal static
objects, but _don't_ make them local to functions, instead define them at
file global level, like:

static MyObject dont_make_that_local;
int user_func(int) {
  do_something_with(&dont_make_that_local);
}

This works on most platforms. But generally of course, don't use them at
all.


Ciao,
Michael.
