[Bug tree-optimization/26570] -fprofile-generate -fprofile-use cause memory corruption immediately

["nmiell at comcast dot net" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from nmiell at comcast dot net  2006-03-05 23:31 -------
On FC4 AMD64, compiling:

#include <algorithm>

void rotate(int x[3])
{ 
        std::rotate(&x[0], &x[1], &x[2]);
}

int main(int argc, char* argv[])
{
        int x[3] = { 0, 1, 2 };

        rotate(x);

        return 0;
}

with: g++ -O2 -fprofile-use rotate.cpp -o rotate
using: g++ (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8)
results in:
/usr/lib/gcc/x86_64-redhat-linux/4.0.2/../../../../include/c++/4.0.2/bits/stl_algo.h:
In function ?_EuclideanRingElement std::__gcd(_EuclideanRingElement,
