What is SHMLBA for this configuration?  [grep -sr SHMLBA /usr/include]
And on the same topic, what is the page size?  [grep -sr PAGE_SIZE /usr/include]
Every successful mmap() return value happens to be a multiple of 0x2000 (8KiB);
there are no odd multiples of 0x1000 (4KiB).
[Some ARM machines have an SHMLBA of 0x4000 (16KiB) even though the page size is 0x1000 (4KiB).]

Construct a standalone test program whose sole action is that call to mmap().
Does the mmap() succeed there?
