    Cgo writes C function declarations pretending every arg is a pointer.
    If the C function is deferred, it does not inhibit stack copying on split.
    The stack copying code believes the C declaration, possibly misinterpreting
    integers as pointers.
    
    Probably the right fix for Go 1.3 is to make deferred C functions inhibit
    stack copying.
    
    For Go 1.4 and beyond we probably need to make cgo generate Go code
    for 6g here, not C code for 6c.
