title: QtSpim cuts the 2 initial chars after string reading
body: <p>I've tried with both QtSpim 9.1.16 and 9.1.17, all of them "cut" the first 2 chars of an input string, setting them to <code>0x0</code>, other ASCII chars are correctly saved into buffer. That's my snippet, even though other code I've found on the internet brings to the same result:</p>
  
  <pre><code>.data               # ROM area
      str_input:  .asciiz "Digita la stringa che vuoi controllare (max 10 caratteri): "
  
  .data               # RAM area
      buffer:     .space 11
  
  .text
  .globl main
      main:   li $v0, 4
              la $a0, str_input
              syscall             # syscall to print user message
              #------
              la $a0, buffer
              li $a1, 11
              li $v0, 8
              syscall
  </code></pre>
  
  <p>For example, if  I type in '12345', that's the memory dump:</p>

  <p>Am I missing something about QtSpim?</p>
