The command line is:

$ ./CoreTest
Segmentation Fault

It runs a small test case reproducing the problem.
I attach the two preprocessed sources: Core.ii and CoreTest.ii.
Here is the stack trace produced by gdb:

I put the main function itno a separate file, but you want only one
attachment...
The source is trivial anyway:

$ cat CoreTest.cc
#include "Core.h"

int main() {
    ThrowException();
    return 1;
}
