One thing I missed: `uintmax_t` doesn't work on 32 bit systems:

    ::error file=clar.c,line=879::clar.c:879:8: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
      879 |        (uintmax_t)p1, (uintmax_t)p2);
          |        ^

I'm inclined to just use "%p" instead and accept that this has
platform-dependent behaviour. Means we'll have to drop the test for
this, but that's the lesser evil from my point of view.

As long as %p works everywhere and with stable output, that is the
most appropriate solution, I would think.  After all, this is used
only for "oops, the test expects these two pointers are pointing at
the same address, but they differ; they point at these places...".

To test such a test, wouldn't it be sufficient to perform "does it
give a bit of output or not?" check in isolation?
