Windows 8.1 x64, dmd 2.066.1:

import std.range, std.stdio;

void main () {

     stdout = File("in.txt", "w");

     'a'.repeat(100000).writeln;
}

import std.stdio;
import std.cstream;

void main () {

     freopen("in.txt", "r", din.file);
     freopen("out.txt", "w", dout.file);

     char[100000] a;

     scanf("%s", a.ptr);

     int lenA;
     foreach (i; 0 .. 100000) {
         if (a[i] == 'a')
             ++lenA;
         printf("%c", a[i]);
     }

     printf("\n%d\n", lenA); // 32767
}

By the way, in Ubuntu 14.04 LTS (dmd 2.066.1) everything works
fine:
#!/usr/bin/rdmd

import std.range, std.stdio;

void main () {

     stdout = File("in.txt", "w");

     'a'.repeat(100000).writeln;
}

#!/usr/bin/rdmd

import std.stdio;
import std.cstream;

void main () {

     freopen("in.txt", "r", din.file);
     freopen("out.txt", "w", dout.file);

     char[100000] a;

     scanf("%s", a.ptr);

     int lenA;
     foreach (i; 0 .. 100000) {
         if (a[i] == 'a')
             ++lenA;
         printf("%c", a[i]);
     }

     printf("\n%d\n", lenA); // 100000
}
