stratcliff.c has
int size = sysconf (_SC_PAGESIZE);
int nchars = size / sizeof (CHAR);
...
adr = (CHAR *) mmap (NULL, 3 * size, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANON, -1, 0);
...
mprotect (adr, size, PROT_NONE);
mprotect (adr + 2 * nchars, size, PROT_NONE);
adr += nchars;
...
CHAR *cp = MEMCHR (&adr[outer], L('V'), 3 * size);
memchr is called with size which contains unreadable pages. How
does it work on any arch?
