Hi all,<br> I come with another problem with the same code as earlier:<br><br>// some preamble code<br><br>// I declare a registration type through:<br><br>printf("1\n");<br><br>typedef itk::ImageRegistrationMethod<BFrameType, BFrameType> RegistrationType;<br>
RegistrationType::Pointer registration = RegistrationType::New(); <br><br>printf("2\n");<br><br>//Then I associate various things to it<br><br>registration->SetFixedImage( ref ) ; <br> registration->SetMovingImage( flt );<br>
<br> registration->SetOptimizer( optimizer );<br> registration->SetTransform( transform );<br> registration->SetInterpolator (interpolator ); <br> registration->SetMetric( metric ); <br><br>// rest of the code<br>
<br><br>After compiling (MSVC2010, Release mode), and running the application, I get the following error:<br><br> <b>System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.</b><br>
Using the "printf" method of debugging, I can see that it prints 1, but not 2 above, implying that the creation of the smart pointer is throwing<br>the exception? <br><br>Curiously, the application runs to completion in the Debug mode. I am using the appropriate Itk libs as per configuration (Debug, Release).<br>
What could be going on here? <br><br>Thanks as always,<br>Sid. <br><br><div class="gmail_quote">On Fri, Nov 4, 2011 at 9:54 AM, Siddharth Srivastava <span dir="ltr"><<a href="mailto:siddys@gmail.com">siddys@gmail.com</a>></span> wrote:<br>
