Again, just FYI, with a simpler example, and with -march=native replaced by
k8 or athlon64.

Source code:

int main(void) {
    static int foo[4];
    int i;
    for (i = 0; i < 4; i++)
        foo[i] = 0;
    return 0;
}

Compile and run, using Cygwin's current gcc version 4.3.4: 

    gcc -O3 -march=athlon64 foobar.c
    ./a.exe
    Segmentation fault (core dumped)
