title: What's causing certain PHP function names to crash PHP?
body: <p>I was programming a client user database this afternoon when I noticed PHP starting to crash without a parse error -- in what I can only assume was a segmentation fault. I tried narrowing down the problem until I realized when I renamed certain functions, they would stop crashing. This is the most bizarre PHP bug I've ever encountered. Here are some of the function names causing the problem:
  <br><br>
  create_user_account() - crashes<br>
  renamed to create_user_email() - works<br>
  check_user_email() - crashes<br>
  renamed to check_user_account() - works<br>
  <br>
  I'm at a total loss on what could be causing this error. Any help in tracing the issue or diagnosing the problem would be appreciated.</p>
