title: Valgrind error differ in operating systems
body: <p>I use valgrind to debug my application. I have two machines where I want to run the code without errors.
  One is an ubuntu 11.10 with valgrind 3.7.0 running and one is a Mac OS X 10.7.2 with valgrind 3.6.0 and valgrind 3.8.0.</p>
  
  <p>I run the following valgrind command:</p>
  
  <pre><code> valgrind --track-origins=yes ./my_program
  </code></pre>
  
  <p>On the Linux machine I did not get any error reports. On the Mac valgrind complains about </p>
  
  <pre><code>==35723== Conditional jump or move depends on uninitialised value(s)
  ==35723==    at 0x10004DCAF: boost::spirit ...
  </code></pre>
  
  <p>As the error is reported in a boost lib I do not think that there might be an error in the boost libraries (boost version is the same on both machines 1.46.1). </p>
  
  <p>What can be the cause for the different error reports?</p>
