But, i am getting “Segmentation fault” when i run the example from the  
README

ruby foo.rb foo.rb:5: [BUG] Segmentation fault  
ruby 1.8.7 (2010-04-19 patchlevel 253) [x86\_64-linux], MBARI 0x6770,  
Ruby Enterprise Edition 2010.02  
Aborted

CODE:  
require ‘rubygems’  
require ‘memprof’  
Memprof.track {  
100.times{ “abc” }  
100.times{ 1.23 + 1 }  
100.times{ Module.new }  
}
