title: GDB is not displaying hexadecimal values for stack
body: <p>I'm trying to have GDB display the hexadecimal values for the stack, so I used the command <code>x /48b $esp</code>, which is a command that I saw on the Internet that should show the hexdecimal values for 48 bytes on the stack starting at the location pointed to by the stack pointer. However, when I do this command I get integer values (some negative instead). An example is show below:</p>
  
  <pre><code>(gdb) x /48b $esp
  0xbffff200: 40  -14 -1  -65 24  -114    4   8
  0xbffff208: 123 0   0   0   0   0   0   0
  0xbffff210: 16  0   0   0   -3  -112    17  0
  0xbffff218: -18 64  27  0   -1  -1  -1  -1
  0xbffff220: 88  40  19  0   45  -9  17  0
  0xbffff228: 38  38  -64 -14 -1  -65 -64 -14
  </code></pre>
  
  <p>I've had this command work before (as far as I know it was the exact same command), however all of a sudden it seems not to be working. Any ideas?</p>
