<p>There are many other frameworks, tools and libs that can help such as Castle ones, Ninject, Nunit, NLog etc.</p>
<p>But i believe that the better response to your question is "It depends".</p>

<p>My Windows/C++ application allocates ~1Gb of data in memory with the operator <code>new</code> and processes this data. After processing the data is deleted.</p>
<p>I noticed that if I run the processing again without exiting the application, the second call to the operator<code>new</code> to allocate ~1Gb of data ... | <p>I don't think this is a Windows problem. Check if you used delete or delete[] correctly. Perhaps it would help if you post the code that is allocating/freeing the memory.</p>

<p>I had data in XML that had line feeds, spaces, and tabs that I wanted to preserve in the output HTML (so I couldn't use <p>) but I also wanted the lines to wrap when the side of the screen was reached (so I couldn't use <pre>).</p>
| <p>Another way of putting this is that you want to turn all pairs of spaces into two non-breaking spaces, tabs into four non-breaking spaces and all line breaks into <code><br></code> elements. In XSLT 1.0, I'd do:</p>
