I'm just trying to define a V3d_Light in order to use it with a V3d_Viewer.
The SetColor results in a segmentation fault, gdb returns :
Program received signal SIGSEGV, Segmentation fault.
0xb4faaacc in V3d_Light::SetColor (this=0xfefd0000, aColor=@0xfefd0000) at ../../../inc/Handle_Visual3d_Light.hxx:78
Am i doing something wrong ?
