title: Fortran bus error on mac
body: <p>The following Fortran code is giving me a bus error on my Mac but no errors when I run it on my Linux machine:</p>
  
  <pre><code>  PROGRAM TINY
    WRITE(UNIT=*, FMT=*) 'Hello, world!'
    END
  </code></pre>
  
  <p>My understanding is that a bus error occurs when the program attempts to access impossible memory but I do not understand where such an attempt has been made in this program. My MacBook has GCC 4.4.0 and my Linux machine has GCC 4.3.2. Any ideas as to why this error occurs?</p>
