static class member deallocation

Hello,

I use a CvMat* as static class member.

The memory is allocated within the static variable declaration (see
code below).

CvMat* MultiCameraModel::Camera_Param_Common_System::m_geometry =
cvCreateMat(3,3,CV_64F);  

With the given code, there is a memory leak, because the data from
CvMat* is not free'd.

Where or how can i deallocate the memory for the static CvMat* (I know
that it is done via cvReleaseMat)? Doing it in the destructor-function
would be a bad idea, since it has a static lifetime.

best regards,
gerd
