In C++ it is fully working:

char s[200005], t[200005];
scanf("%s%s", s, t);

Indeed.

Generate a 100000-character string:
-----
import std.range, std.stdio;
void main () {'a'.repeat (100000).writeln;}

Try to copy it with D scanf and printf:
-----
import std.stdio;
void main () {
        char [100000] a;
        scanf ("%s", a.ptr);
        printf ("%s\n", a.ptr);
}

Only 32767 first characters of the string are actually copied.
