in my cRenderSystem class I have a list of shaders like this

class cRenderSystem {
...

 std::list< cShaderBase* > m_Shaders;

public:
...

 void RegisterShader( cShaderBase *shader );
};

so my problem is when the engine shutdown it crash becouse it try to clear the m_Shaders list if I do it myself like this m_Shader.clear() then it will crash the same way. when I debug it I got this message from the debug thing of one of the members in my Shader "CXX0030: Error: expression cannot be evaluated" I usally get this error when I try to use an unallocated class example: cMyClass *myClass; cout << " Value One: " << myClass->firstValue << endl; the shader has not been deleted becouse it hasn't logged it self in my .log -file as it do when it is destroyed from it's destructor.

well... std::list then

but it doesn''t solve my problem though

Hello McZ,

If I recall since all you have is a list of pointers a clear on the list should not call anything or even delete the pointers.
It just remove the internal list object that holds your pointers.
It your job to go though and delete the pointers.

So it should not carsh at what your doing.
Have you tried to step into the clear of the list?

If you had a list of actual object then on a call to clear() the list would call each destructor.
