title: Colon at end of section directive causes segfault
body: <p>It's a semi-common error for me to accidentally include a colon (<code>:</code>) at the end of a <code>section</code> directive:</p>
  <pre><code>section .text:
      _start:
  </code></pre>
  <p>When done to the <code>.text</code> section, this causes a <code>SIGSEGV</code> before the first instruction can be executed though, and I'm curious as to why.</p>
