FreeBSD 11 (i386) and also Ubuntu 12.04 (32 bit):
After configuring BIND with --enable-developer (and --disable-atomic to overcome the issue identified in #46324), "make" failed with:
ht_test.c: In function 'test_ht_full':
ht_test.c:63:36: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
result = isc_ht_add(ht, key, 16, (void *) i);
^
In file included from /home/stephen/bind9/unit/atf/include/atf-c.h:34:0,

... and several other similar errors in the same file.
True, --enable-developer promotes warnings to errors and the unit tests can be built without this flag. However, the test appears to be assuming a particular pointer size.
