Is it fixed for 64-bit as well as 32-bit? I was > concerned that "the size of a word" might actually be imprecise and should be > sizeof(void*) not sizeof(int). It is. In fact, I found the following comment in the OpenSolaris sources of memalign.c, still in Illumos: https://github.com/illumos/illumos-gate/blob/master/usr/src/lib/libc/port/gen/memalign.c#L35 #define _misaligned(p) ((unsigned)(p) & 3) /* 4-byte "word" alignment is considered ok in LP64 */
