I ran purify, glowcode and True coverage on my application and found out that
the memory leak is NOT in vtk. MFC behaves strangely when you load multiple
mixed dlls. MSDN claims that these are not</span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Really leaks, but report of error ( the
MSDN title and question number are attached below) which can be ignored.(could
say typical of Microsoft). But what should be noted is that when there is an
error (an actual memory leak ) in your dll then also it gives you the same
error message. So it is left up to you to verify in which category you belong.</span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Also if you are using smart pointers
in your application (along with multiple dlls) beware, if the exit sequences of
the dlls are not alright then these smart pointers do not get freed smarlty you
have to manually call a Release() on these pointers. </span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

test your application for memory leaks (purify has a trial release of their
tool for free) </span></font></p>
