[vtkusers] Attribute AllocatedRenderTime from vtkProp are a nan - VTK CVS HEAD

[Francois Bertel]

Hello,

In your program, enable the floating point exceptions with:

#include "vtkFloatingPointExceptions.h" // this file is in VTK/Common

int main()
{
vtkFloatingPointExceptions::Enable();

// rest of your program here.
}

It then will crash where the first exception happen, probably because
of a division by 0. After locating, the line that triggers the
exception, you will be able to try to figure out why it happens.
