        <pre>The application works well when built by Clang 32bits and MSVC both 32 and
64bits, but it crushes when built by Clang 64bits.
Code:

#include <stdio.h>

void foo()
{
    try {
        throw 1;
    }
    catch (int x) {
        printf("Catch %d\n", x);
        try {
            try {
                throw 2;
            }
            catch (int x) {
                printf("Catch %d\n", x);
                throw 3;
            }
        }
        catch (int x) {
            printf("Catch %d\n", x);
        }
    }
};

int main()
{
    foo();
    printf("Successfully exit\n");
