Hi Eric,

unfortunately the following program crashes also exactly in the same way as
the add-in:

#include <iostream>
int main(int argc, char* argv[])
{
        char* p = "Test";
        p[0] = 'P';
        std::cout << p;
        return 0;
}

It doesn't matter which compiler switches I use to compile it - either in the
ide or via the command line. It crashes even if I compile it like that:
cl Test.cpp
My compiler version is 13.10.3077

It seems to me that my compiler is placing string literals _allways_ in
readonly memory disregarding the compiler switches I use .....

Thanks & Regards
Plamen
