MSLException hanldle and cause are empty

I am trying to port some 2012B Simulink code into 2016B and I get

---------------------------------------------------------------------- Unable to generate code using bus object 'struct_gXHXfJxyCgdYSgjadAsrfG' because it has an element named 'const' which conflicts with a programming language reserved identifier -----------------------------------------------------------------------

both cause and handle in MSLException are empty.

There is no 'const' in the model, there are Constant blocks.

The error occurs if you use elements of a MATLAB structure as block parameters, and the structure has element names that are reserved words in C. To work around the error, change the element names so they do not conflict with reserved words. For example, use x._const instead of x.const.

I hope this helps.

I understand THAT, but which structure is it? 'struct_gXHXfJxyCgdYSgjadAsrfG' is not telling me much...
