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.
