title: GDB kind of doesn't work on macOS Sierra
body: <p>It is a problem that appeared when I first updated to macOS Sierra yesterday.</p>
  
  <p>GDB itself is running OK. However, somehow, it cannot run my program. When I type 'run' and 'enter', it immediately crashes with the information:
  <code>During startup program terminated with signal SIG113, Real-time event 113.</code></p>
  
  <p>My GDB is based on homebrew. So today, I uninstalled the whole homebrew package and reinstalled it. After the codesign step, I still faced the same error.</p>
  
  <p>I tried 'sudo' and a few other things. Google had no idea what happened. So I was wondering if you guys might have some magical solution.</p>
