Compiled Matlab code crashes when /clr is not selected

I'm wondering why the code I'm using with a compiled Matlab library crashes when a common language runtime is not selected. For a minimal example, I've tried compiling the following Matlab function into a shared library:

function [volOut, volAvg]=testVarPass(volIn)
volOut=double(volIn);
volAvg=mean(volOut(:));
end

using the following call to mcc: mcc -B csharedlib:mylib testVarPass.m

Next, I've set up a Visual Studios 2010 Console Project.

#include "stdafx.h"
#include "matrix.h"
#include "mylib.h"
int _tmain(int argc, _TCHAR* argv[])
{
    mxArray *vol_in;
    mxArray *vol_out;
    mxArray *vol_avg;
    mwSize dim_list[3];
    double *vol_avg_ptr;
    dim_list[0]=10;
    dim_list[1]=10;
    dim_list[2]=10;
    if( !mclInitializeApplication(NULL,0) ) { //initialize Matlab Compiler Runtime
        return -1; 
    } 
    if (!mylibInitialize()) //initialize library
    { 
        return -2; 
    }
    vol_in=mxCreateNumericArray(3,dim_list, mxINT16_CLASS, mxREAL);  //make a sample 3d array
    mlfTestVarPass(2, &vol_out, &vol_avg, vol_in); //crashes here
    vol_avg_ptr=mxGetPr(vol_avg);     
    /* Call the MCR and library termination functions */ 
    mylibTerminate(); 
    mclTerminateApplication();
    return 0;
}  

If I build the project with Common Language Runtime Support set to: /clr...everything works fine. If I build the project with Common Language Runtime Support set to: nothing...first, the debugger vomits many exceptions when mylibInitialize is called. The most common are: varflowFailed, tffFailed, CryptoPP, jitCgFailed, and xsd_binder::MalformedDocumentError. Second, the mlfTestVarPass call crashes with an access violation.

I, and a programming I'm working with, are wondering why.
