Simulink C1061 Compiler Error

Hi all,

I'm running MATLAB 2012a with VisualStudio 2005 as the C++ compiler. I have recently run into an issue when generating C++ code from a Simulink model. Apparently, this is a known issue with VS2005:

http://support.microsoft.com/KB/315481

The make error points to generated code in the slprj, which clearly does not have 255 (or whatever the limit) of nested loops. It has only 2 or 3 nested loops. However, because of this, the code does not get past this step to generating code in the ert_rtw folder that I need to deploy on a real time system. Short of upgrading to MATLAB 2014a and testing Visual Studio 2013, I can't think of a solution. Has anyone encountered this issue and resolved it?

c2_filename.cpp(7176) : fatal error C1061: compiler limit : blocks nested too deeply NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio 8\VC\BIN\cl.exe"' : return code '0x2'

When I check line 7176, it looks fine.

EDIT: I uncovered that the issue is not related to the code I added, but rather, to signals that I have added to a bus initialization file. I'm not sure why adding one more signal to the bus causes issues. It seems like in the c2_filename.cpp, there are a lot of UNNESTED loops, which is causing the Visual C++ compiler to throw the C1061 error; this is a KNOWN bug. However, it looks like 2012a 32-bit only supports C++ compilers with these bugs...
