code replacement of sigabrt

Generating embedded C code that can be run instide a C++ simulation.

Would like the embedded C code to "crash" gracefully so that the higher level simulation can terminate correctly and allow a debug option to be set inside the C-code to view the program at the point of failure.

What are my options? Can the embedded C-code use code replacement to change the abort function call to raise another signal that could be caught by the calling C++ program?
