```

[In GCC 12 the new parameter `min-pagesize` is added and defaults 4 kB.][1]
It treats INTEGER_CST addresses smaller than that as assumed results of
pointer arithmetics from NULL while addresses equal or larger than that
as expected user constant addresses. For GCC 13 we can represent results
from pointer arithmetics on NULL using &MEM[(void*)0 + offset] instead
of (void*)offset INTEGER_CSTs.
