I tested this file with MegaPOV 0.5a and POV-Ray 3.1g (when all
the photon-related stuff is commented out).
Linux RedHat 6.1 (2.2.12-20smp) :
- MegaPOV crashed at the point described above.
- POV works fine with official compile (static libpng ?) and
unofficial compile with dynamic libpng.
SGI IRIX 6.5 :
- both works (POV is unofficial compile)
Digital UNIX V4.0F :
- MegaPOV Floating exception when starting render (X display is open)
so it is again something different (I didn't trace that crash yet).
- POV works (unofficial compile)
Guess what ? Needs some works around ;-)

BTW, ton boulot sur PvMegaPOV est super, mais je n'ai malheureusement
jamais pu installer PVM sur nos machines (suis pas root). Quid d'une version
MPI ? {hehehehe}
