Hi all:
My operation os:windows 7 x64 using opencv x86.

I using below list,it works well.
<pre><code class="cpp">
calcHist(&c1,1,0,Mat(),hist,1,&histSize,&histRange,true,true);
</code></pre>


But I change ninth parameters from "true" to "flase", then throw expection.
<pre><code class="cpp">
calcHist(&c1,1,0,Mat(),hist,1,&histSize,&histRange,false,true);
</code></pre>
