Loads/stores not "naturally" aligned: 4-byte boundaries for 4-byte data, 8-byte boundaries for 8-byte data. In the late 90s I would routinely get bus errors while running Netscape on SPARC Solaris machines, presumably due to corner-case unaligned memory accesses. x86 processors perform unaligned loads and stores, but at a slight speed penalty, and with the loss of atomicity.
