Sorry. PEAR Version: 1.9.4 PHP Version: 5.2.17 Zend Engine Version: 2.2.0 Running on: Linux DiskStation 2.6.32.12 #3211 Tue Apr 16 20:03:28 CST 2013 armv5tel Apache 2.0 What else should I provide? Thank you.

Hi @virtual7, you should report this to https://github.com/facebook/xhprof.

I tried, but there is no "Issues" menu. How can I submit a bug? Thank you.
