[Paraview] Selection frustrum problem

[Mattijs Janssens]

Just something I noticed.

Our reader module (for OpenFOAM) installs a malloc 
routine (through __malloc_hook) which initialises 
all memory to NaN. It also sets floating point 
trapping (FE_DIVBYZERO | FE_INVALID | 
FE_OVERFLOW). We use this as a simple way of 
catching uninitialised data.

I've noticed that I get a floating point exception 
when I do a cell (or point) selection i.e. it 
seems to use uninitialised data. If I switch off 
the exception handling it works just fine.

I attach a traceback of the error. Lines 0..2 are 
from our exception trapping routine. Last 
vtk/paraview routine is #3, SetFrustum.

Kind regards,

Mattijs
