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

The source is trivial anyway:



$ cat CoreTest.cc

#include "Core.h"



int main() {

    ThrowException();

    return 1;

}
