> tv = my_tv_maker(434.23); // over-write previous tv.
This needs to have a space for the return value as tv can be accessed via
my_tv_maker as the address of it was passed to an extern function.
Think of:
extern TV *a1;
TV my_tv_maker(float tr)
{
TV myTV;
myTV. confidence = tr;
use (a1-> confidence);
return myTV;
}
void other(TV *a)
{
a1 = a;
}
So this bug is invalid as tv in my_subr can be exported for use in my_tv_maker.
