Strange Error from codegen: "Error indenting generated C code"

I'm getting a strange error from the codegen tool.

Using the command:

outDir = 'C:\somedir';
strFileName = 'main.m';
codegen('-g','-c','-v','-config','config','-d',outDir,strFileName);

I get this error:

??? Error indenting generated C code.

Error in ==> main Line: 1 Column: 1
Code generation failed: Open error report.

Any help with this would be greatly appreciated.

Here is the main.m file:

%#codegen

function [ ] = main(  )
global delay counter

      mc_pll_init(); % Initialize the hardware
      mc_lcd_init(); % Initialize the LCD
      mc_led_init();

      mc_lcd_println('Real Time Interrupt',0);
      mc_lcd_println('               ',1);

      delay = 0;
      counter = 0;

   %setup realtime interrupt
      RTICTL = uint8(hex2dec('28'));    % set RTI timming: 8MHz / (9 * 2^11) = 434.02778 MHz or 2.304 ms
      CRGINT = uint8(hex2dec('80'));    % enable RTI interrupt
      CRGFLG = uint8(hex2dec('80'));    % clear rti flag */

      cnt = 1;
      while (1)
        PORTB = uint8(cnt);

        mc_lcd_println('cnt = %-16d', cnt, 1);
        cnt = cnt * 2;
        if (cnt > 255)
            cnt = 1;
        end
        mc_timer_wait(20);
    end
  end

and here is the configuration of the coder object config passed in the command line (any configuration settings not listed are default):

config = coder.CodeConfig;
config.Name = 'Real-Time Workshop';
config.Description = 'Generic Real-Time Target';
config.TargetLang = 'C';
config.Verbose = true;%false;
config.GenCodeOnly = true;
config.GenerateMakefile = false;
config.GenerateReport = false;
config.LaunchReport = false;
config.FilePartitionMethod = 'SingleFile';
config.MaxIdLength = 31;
config.CCompilerOptimization = 'off';
config.CCompilerCustomOptimizations = '';
config.MakeCommand = 'make_rtw';
config.TemplateMakefile = 'grt_default_tmf';
config.PostCodeGenCommand = '';
config.CustomHeaderCode = '';
config.CustomSourceCode = sprintf('#include "MCU.h"');
config.CustomInitializer = '';
config.CustomTerminator = '';
config.CustomInclude = '';
config.CustomSource = '';
config.CustomLibrary = '';
config.ReservedNameArray = '';
config.ConstantFoldingTimeout = 10000;
config.InlineThreshold = 10;
config.InlineThresholdMax = 200;
config.InlineStackLimit = 4000;
config.SaturateOnIntegerOverflow = true;
config.StackUsageMax = 200000;
config.EnableVariableSizing = true;
