When that return string will be freed?

What about:

extern(C) auto example(....)

?

to!string allocates on the GC heap when given a char* (it has to, 
in order to safely produce immutable data in the string).

It will be freed by the first garbage collection ocurring after 
all references to that memory are dead.
