That works, but I misrepresented the problem and found that the following may be the issue (this looks more like the code im using):

import std.conv, std.stdio;

void main()
{
    string[] strArr;
    foreach(int i; 0 .. 257) {
        strArr ~= text("Line: " ~ to!string(i));
    }
    
    foreach(string e; strArr) {
        writeln(e);
    }  
}

// OUTPUT for first 87 lines
Line: 2
?O 
?O 
`O 
@O 
 O 

?N 
?N 
...
ect....
...
?@ 
?@ 
`@ 
0@ 

Line: 88
 /* rest of output is as expected */

Changing 257 to 256 gives you what you would expect.
