[Insight-developers] Dashboad: Looking at Valgrind

[Luis Ibanez]

Hi Brad,

Thanks for pointing this out.

Here is the summary of valgrind builds from clownfish
since December first.:

http://www.cdash.org/CDash/index.php?project=Insight&date=2010-12-14&filtercount=3&showfilters=1&filtercombine=and&field1=site/string&compare1=63&value1=clownfish&field2=hasdynamicanalysis/bool&compare2=0&value2=&field3=buildstarttime/date&compare3=83&value3=december%201%202010

I believe that this machine is doing different sections
of the toolkit on different days, so comparing one day
to the next may not be representing a real increase or
decrease in the number of issues.

That said,
you have a point in that the number of
issues should be zero anyways               :-)

The problem with the itkGaussianMembershipFunction.txx
is the lack of initialization for m_Mean in the constructor.

I just pushed a patch to Gerrit for this issue:
http://review.source.kitware.com/#change,576

This takes care of the following:

itkGaussianMixtureModelComponentTest<http://www.cdash.org/CDash/testSummary.php?project=2&name=itkGaussianMixtureModelComponentTest&date=2010-12-16>
http://www.cdash.org/CDash/viewDynamicAnalysisFile.php?id=996928

itkGaussianMembershipFunctionTest<http://www.cdash.org/CDash/testSummary.php?project=2&name=itkGaussianMembershipFunctionTest&date=2010-12-16>
http://www.cdash.org/CDash/viewDynamicAnalysisFile.php?id=996927

itkSampleClassifierFilterTest7<http://www.cdash.org/CDash/testSummary.php?project=2&name=itkSampleClassifierFilterTest7&date=2010-12-16>
http://www.cdash.org/CDash/viewDynamicAnalysisFile.php?id=996926


Thanks


   Luis
