Just a short note…
./lalloc.c:#define ALLOC_ISUNALIGNED(p) (((ptrdiff_t)(p)) % ALLOC_SIZE)
./lalloc.c: if (ALLOC_ISUNALIGNED(ptr))
./lalloc.c: || ALLOC_ISUNALIGNED(lp)
… and…
./histrap.c: if ((ptrdiff_t)hp < (ptrdiff_t)history) {
./histrap.c: } else if ((ptrdiff_t)hp > (ptrdiff_t)histptr) {
… these are probably not safe. Hell, any signed types
are probably not safe, in C, unless proven otherwise.
mksh probably should not use ptrdiff_t a̲t̲ ̲a̲l̲l̲, just size_t.
Discovered by the size_t/ptrdiff_t asymmetry on s390 being
discussed in various places.
