Backticks segfaults occasionally

[brad@…]

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.

/Users/brad/projects/gately/Gately.app/Contents/Resources/lib/panel.rb:65: [BUG] Segmentation fault

This should be fixed in trunk.
