Are you doing any file I/O in your scene?  If so, make sure you have the 
proper closing parantheses in your #write directives.  In my current 
project, I missed one and it would cause POV-Ray to crash with the error 
you gave.  For example, this:

#write (file2,"
         object {
                 TrackTie
                 Reorient_Trans(y,",raxis,")
                 Reorient_Trans(z,",(point2-point1)*(x+z),")
                 Reorient_Trans(",(point2-point1)*(x+z),",",point2-point1,")
                 translate ",point1,"
                 pigment { color rgb <1,1,0> }
         }"

Notice the missing ")" at the end?  That's what was causing my problem.
