 Hi, I have a script that is running an external command using backticks ``
 every 5 seconds or so. It seems to work for a few hours, then segfault.
 The error report is below. From what I can tell, the string passed into
 the backticks is not null - i can print it out using NSLog just fine.

 I haven't been able to provide a quick way to replicate this problem - it
 seems to take time.

 This is on the latest svn of MacRuby.
