Hi,

I would quickly like to recommend Dan Moulding's 'Visual Leak Detector'. Of what I know about, it is the most easy to use non-commercial leak detector on Windows (when you are developing with Visual Studio .Net).

Edit (the link): http://dmoulding.googlepages.com/vld

Pros: tine, free (LGPL), can be enabled/disabled per code block
Cons: lib+dll, visual studio only, ...

It is probably possible to recompile the code into a static lib, if you want to.

Your code from before with VLD looks like this

Code: Select all

#include

// #define EIGEN_DONT_ALIGN // compiles ok now if EIGEN_DONT_ALIGN
#include

USING_PART_OF_NAMESPACE_EIGEN

int main( int argc, char* argv[] )
{
  new int(123); // memory leak!

  MatrixXf a;
  a = MatrixXf::Zero( 123, 123 );
  return 0;
}


and it produces the following clean output (it even allows you to follow the call stack via double-clicks)

Code: Select all

Visual Leak Detector Version 1.9h installed.
