The following scene gives an error.

#version unofficial megapov 1.2;
#include "mechsim.inc"
global_settings{
  mechsim{
    method 1
    bounding 0
    gravity <0,0,0>
    time_step 0.1
    step_count 10
    topology{
      MechSim_Generate_Block(
        <0, 0, 0>, 0.08, 20, 1000, 2000,true,
        <0, 0, 0>, <1, 1, 1>, <4, 4, 4>, No_Trans, 3
      )
    } // end topology
  } // end mechsim
} // end global_settings
MechSim_Show_Objects(0, 0, 0, -1, -1, -1, -1, false, -1, "")

The POV-Ray core rendering code threw an unhandled exception
...

By commenting out the time_step or step_count the file renders.

Can' reproduce that - please post the usual information (hardware and 
OS).  It might also be useful to know when exactly the error occured.

windows lists it as
Win 98 se
AMD Athlon XP 2200+  256mb

While I was trying to get a minimum scene and isolate the problem, I
sometimes got as far as "Generating Grid...Done". The sample I gave always
stopped before this.

This is strange since if it does not get past the 'Done' the error 
occurs even before the simulation has started.

Note that the simulation in your example gets instable - this is not 
detected in the first 10 steps so you don't get an error message.  Try 
setting time_step to 0.001 to check if that's the cause of the problem.
