This is a reverse engineered, minimized version of a crasher that I have experienced when trying to print, with Canon's SELPHY printer driver PDE (plug-in) installed.

int main()
{
    int                     i, j, k;
    char                    *p, *q;

    i = GetCountOfLoginItems(u);

    for (j = i; j > 0 ; j--)
    {
        p = ReturnLoginItemPropertyAtIndex(u, 1, j-1);
        q = p;
        k = strcmp("foobar", q);
    }

    return 0;
}

Adobe AIR (up to 4.0, not fixed yet) is also affected by this same "crasher" which seems to be triggered by a specific system preference state (i.e. my machine), but it doesn't seem to be limited to my specific case.

The AIR bug is reported here:
