I discovered a quite funny bug by accident. This happened in the SunOS
compile of povray 3.1g. I don't know what happens with other versions.

  My intention was to type the command line parameter +sp4 but typoed and
I typed +ap4 by mistake. This is a quote from the information output by
povray:

  That's weird, Warp. What was the rest of the command line? Did the scene
render properly?

./x-povray -i test -w320 -h240 +ap4

  Yes.
  That huge number seems to be always the same so it doesn't seem to output
just random garbage.

  PS: I don't know if it's relevant, but Sparcstations use 128-bit long
doubles (and 64-bit doubles).

  I just noticed that this sentence might be a little non-understandable.
What I meant was:
  In Sparcstations the type 'long double' is 128 bits (and the type 'double'
is 64 bits).
