How do you use a debugger like GDB with a Rapid Accelerator Simulink simulation?

I have a Simulink model that I run in Rapid Accelerator mode using the sim() command from within a script. The model contains multiple C/C++ S-Functions that get compiled with mex using the -g flag for debugging symbols. The simulation runs without issue in Accelerator mode, but when I run it in Rapid Accelerator mode, I get a SIGFPE (Floating Point Exception) signal. I've been trying to use GDB to debug this issue, but I can't seem to get it to break on the SIGFPE. When using GDB, I attach to the MATLAB process and then execute the sim() command in MATLAB. However, since RAccel mode runs the sim in a new thread (or process?), I don't know if these are the appropriate steps. Any help would be greatly appreciated. Thanks!
