Pooma where and peephole optimization in CW

Gang:
I have been trying to get our code (Tecolote 4.0/Pooma R2) to compile optimized under Metrowerk's Codewarrior off and on for quite some time. The problem always seemed to be in files which contained a Pooma where statement involving a Field<MT,double,ET>. Interestingly, I could compile code using where statements of type Field<MT,Vector<Dim,double>,ET>.

Anyhow, through sheer perseverence I have been able to determine that it is the peephole optimization which is causing the problem (an internal compiler error). When I turn this option off, I can turn every other optimization option on to its highest value and get it to work. Since Metrowerk's pays more attention to you guys than to me, I thought someone might like to code something like:

   // Make a CompressibleBrick-Engine-based field.

  Field<UniformRectilinear<2>, double, CompressibleBrick>
    fc(cell, layout1, origin, spacings);

  // Test the where statement for a scalar field
    fc = -1.0;
    fc = where(fc > 1.0e-16, fc, 0.0);

  std::cout << fc << std::endl;

and turn the peephole optimizer on and see if they get the same problem.

Error   : internal compiler error: File: 'Operands.c' Line: 814
BasicTest1.cpp line 146   }

Thanks,
John
