Hi all,

I'm using vtkGPUVolumeRayCastMapper to render some datasets. All
things works fine, but in one condition, when I set the zoom, the
property AllocatedRenderTime from vtkProp acquires a NAN value, and,
of course, the application crashes. I really don't know what can turn
this property in a NAN, then I'm asking here if someone knows. This
will helps me to find the problem, and if necessary, fill the bug
and/or suggest a path.
Only to help, here are my backtrace:
