Link error when using MATLAB function block in simulink with linear algebra functions and breakpoint

I'm trying to run a simple MATLAB function block in Simulink like below. In the MATLAB function block I have a simple linear algebra command,

function y = fcn(u)
%#codegen
bla = 10; 
y = rank(u);

It compiles and runs just fine as this. However, if I put a breakpoint in the function so that I can debug, it outputs the following link error.

### Linking ... 
	link.exe /nologo /dll /MANIFEST /OPT:NOREF /export:mexFunction /OUT:testLinearAlgebraFunction_sfun.mexw64 /map:"testLinearAlgebraFunction_sfun.map"      @testLinearAlgebraFunction_sfun.mol 
LINK : fatal error LNK1181: cannot open input file 'Files\MATLAB\R2016a\extern\lib\win64\microsoft.obj' 
NMAKE : fatal error U1077: '"c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\Bin\amd64\link.exe"' : return code '0x49d' 
Stop.

However. if I get rid of the 'rank' function. I am able to set a breakpoint in the function.

From the error meesage, it really just seems like a parsing issue where 'Program Files' are cutoff but I cannot find any easy way to modify the makefile. Thoughts? MATLAB Version is R2016a

Should you use Simulink? Otherwise, Matlab solves all LA problems with over dozens of different ways more efficiently than Simulink blocks.

If you're trying to work with the function flie of MATLAB function block, then it is a different story.

This function file works w.r.t your inserted commands unless there is a illegal operations enforced with a step size, for instance.
