CGIR assertion 'fitsType<size_t>()' failed when Code Generating

I was trying to Code Generate a Simulink model into a dll when I got the following error:

CGIR assertion 'fitsType<size_t>()' failed

Unexpected or internal error encountered in "in CGIR: b:\matlab\derived\win32\src\include\cg_ir\util_prim\../../../../../../src/cg_ir/export/include/cg_ir/util_prim/Size64.hpp line 125: fitsType<size_t>() ". Please report this to MathWorks if you can cause it to recur

I think I've managed to locate the problem to this location:

Any ideas?

According to Matlab support it is due to a bug in Matlab 2011b (possibly older versions too), which was solved in 2012a and later. I updated to 2013b and now I don't get that error anymore.
