[SOLVED] Memory problems in simple app using Sofa as lib

Hello guys,

I have a problem with smart pointers which appear not to be as smart as we want. I have this problem in the simplest application using Sofa as a library. I use a CMakeLists file to link Sofa to my app. In the app, I wrote a simple scene with only one root node, in which I add a Mechanical Object. Other implicit objects are created, but I don’t add them myself.

The compilation went well. However, the app crashes when dealing with the SPtr object of the mechanical object. I had the problem of creating it (in a different context), but here I have problems when destroying it. At the end of the scope, the SPtr object is destroyed, the mechanical object should be deleted. The apps crashes in this delete:

void Base::release()
{
    if (ref_counter.dec_and_test_null())
    {
        delete this; //crashes here!!!
    }
}

This problem does not occur in runSofa. I also wrote a minimal sofa project (in applications/project), and don’t have the problem neither. Do you think it’s related to the way I link Sofa? In this case, could you describe how I should do it? I hope this conversation could also be a start for the documentation of this page: https://www.sofa-framework.org/support/doc/programming-with-sofa/write-a-scene-in-c/ and another describing how to use sofa as a lib.

The CMakeLists I use: http://pastebin.com/KCt0PhSa
I use Windows 10, 64 bits with MSVC 18 to compile. Sofa and the app are compiled in Debug mode. Sofa is compiled from the Git sources.

Thanks for helping
