Here's a slightly shorter testcase. It crashes everything from 3.1 until
3.4 branch.

======================================
int (**foo)(int);

int bar()
{
    static int **s;
    int i, j, k=i, **p;

    (*foo)(**s);
    if ((*foo)(0)) return 0;
    if (k > 0) return 0;

    p = s;
    for (i = 0; i <= k-1; ++i)
    {
        j = (*foo)(0);
        if ((*foo)(0)) return 0;
        **p = j;
    }
}
======================================
