>Description:
Compiling a program with the -m64 flag on solaris 2.7 leads to the fact that excaptions can't be caught any more. The immediate result in a segmentation fault.
>How-To-Repeat:
Use the following program:

#include <stdio.h>
#include <exception>

void throwException()
{
        throw std::exception();
}

int main(int argc, char* argv[])
{
        printf("Hello World!\n");
        try
        {
                throwException();
        }
        catch(...)
        {
                printf("Gotcha, Exception\n");
        }
        printf("Hello World2!\n");
        return 0;
}

Compiling with "g++ ExTest.cpp":
bash-2.03$ ./a.out 
Hello World!
Gotcha, Exception
Hello World2!

compiling with "g++ -m64 ExTest.cpp":
bash-2.03$ a.out 
Hello World!
Segmentation Fault (core dumped)
