<div class="markdown_content"><p>I've compiled GLplot under MS VisualC++ 7.0. In order to achieve this, I've downloaded the original version of third-party mathexpr library, and found a memory leak in mathexpr.cpp there:<br /> s=new char[n]; <br /> // HACK: mlkz memory leak when op == Num || op == Var<br /> switch(op){<br /> case Num:return ValToStr(ValC);<br /> case Var:return CopyStr(pvar-&gt;name);<br /> ............</p> <p>This error can be found in your patched mathexpr.cpp as well. Here is the solution:</p> <p>s=new char[n]; // HACK: mlkz memory leak when op == Num || op == Var<br /> switch(op){<br /> case Num:<br /> {<br /> delete[] s; // PATCH: mlkz<br /> return ValToStr(ValC);<br /> }<br /> case Var:<br /> {<br /> delete[] s; // PATCH: mlkz<br /> return CopyStr(pvar-&gt;name);<br /> }</p></div>
