        PR middle-end/64242
        * gcc.c-torture/execute/pr64242.c (foo, bar): New functions.
        (p): Make it void *volatile instead of volatile void *.
        (q): New variable.
        (main): Add a dummy 32-byte aligned variable and escape its address.
        Don't require that the two __builtin_alloca (0) calls return the
        same address, just require that their difference is smaller than
        1024 bytes.
