I got a memory corruption error trying to render a scene file that uses Ive's
spectral rendering rig.  Here is the message output:

RGB preview rendering.

-----------[END MESSAGES]-----------

The process hangs at this point.  Not even Ctrl-C (SIGINT) can interrupt it:

----------[BEGIN MESSAGE]----------
^C
uberpov: received signal SIGINT: Interrupt; requested render cancel
^C^C^C^C [ad nauseam]
-----------[END MESSAGE]-----------

The same also happens in UberPOV beta 10.  POV-Ray 3.7.0 renders to completion,
with results as expected.

This is the scene file:

----------[BEGIN CODE]----------
//Preview:
// +w300 +h270 +a
#version 3.7;

#include "spectral.inc"

global_settings
{ assumed_gamma 1
  max_trace_level 100
}

camera
{ location -84 * z
  right x
  up y * 0.9
}

#declare Light = SpectralEmission (E_D65);
#default { finish { diffuse 1 ambient Light * 0.25 } }

box
{ -1, 1 scale <72, 72, 96>
  pigment { C_Average (D_CC_A4, 1, D_CC_B4, 1) }
}

plane
{ -z, 0
  pigment { checker D_CC_F4 C_Average (D_CC_A4, 1, D_CC_B4, 1) }
}
-----------[END CODE]-----------

(Yes, I had not yet gotten to defining a light source.)
