Yes, a bug in your code. You never set the length of the result 
string anywhere.

Try to initialize the local string with

Result:= 'xxxxxxxxxxxxxxxx'

and then call your function with

WriteLn (MyIntToStr (11111));
WriteLn (MyIntToStr (2222));
WriteLn (MyIntToStr (333));
WriteLn (MyIntToStr (44));
WriteLn (MyIntToStr (5));

and see what happens...
