Use a MATLAB Function Block in your model containing the following code:

coder.updateBuildInfo('addCompileFlags', '/Zi');
coder.updateBuildInfo('addLinkFlags', '/DEBUG');

Change the compile and link flags to be the appropriate flags for your compiler to produce debugging symbols.

Upon simulation, debugging symbols (if created as a separate file) will be produced in the directory (where <model> is the name of your model):

<currentFolder>\slprj\_sfprj\<model>\_self\sfun\src\

From the stack trace that appears in the Details view of the MATLAB crash window, use a tool that can read debugging symbols to determine the function and line number of each frame in the stack trace.
