[Alleen Wang]

Hi All,

When I use the gdb to run switchboard, I get error message ...

#0 __strcmp_ssse3 () at ../sysdeps/x86_64/multiarch/../strcmp.S:1109
#1 0x00007fffe05abd3e in pantheon_keyboard_layout_page_layout_handler_from_code ()
   from /usr/lib/x86_64-linux-gnu/switchboard/hardware/pantheon-keyboard/libpantheon-keyboard.so

   from /usr/lib/x86_64-linux-gnu/switchboard/hardware/pantheon-keyboard/libpantheon-keyboard.so

I found the bug at "strcmp", and this function call from ...

switchboard-plug-keyboard-0.2.1/src/Pages/Layout/handler.vala

  public bool from_code (string code, out uint l, out uint v)
  {
   var parts = code.split("+", 2);

   l = v = 0;

   if (parts[0] == null) return false;

   while (codes[l] != parts[0]) ///////////////// <---- Bug was here !!!
    if (l++ > codes.length)
     return false;

   if (parts[1] == null) return true;

   while (layouts[l].codes[v] != parts[1])
    if (v++ > layouts[l].codes.length)
     return false;

   return true;
  }

After I remove there, and compile, install. It didn't to crash.

But, it just a simple workaround, not solution.

I am not a developer for this project. I always to need developer for this bug.
So, I just to report some information for this bug.

Thanks!!!
