[osg-users] Error when using osgShadow

[Sebastian Messerschmidt]

Hi David,

Usually there is not much value in a "floating point exception". I guess 
there is an NaN or division by zero, which I observed for empty or 
degenerate scene bounds.
I advise to compile with floating point exceptions disabled, as osg will 
print out errors to the console in those cases anyways (check your 
compiler flags) and osg is not using structured exceptions ...
If you are using Visual Studio you can enable catching exceptions from 
the debugger to see where they are thrown and can provide a call stack, 
so I guess something like this is possible with gdb too.

Also: are the osgshadow examples working?
Cheers
Sebastian
