The object containing the throw and the catch
gcc version 4.7.2 (GCC)
Target: sparc-sun-solaris2.10
Configured with: /proj/vobadm100/svn/gcc_4.7.2/configure \
--prefix /vobs/cello/cade_A_tools_gcc \

--with-isl=/vobs/cello/cade_A_tools_utils/isl
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;
}
