Limits on 4.2BSD lseek(2)?

[Erik E. Fair]

This comes about because the dbm(3) library does not guarantee to
deliver things aligned on the appropriate boundary. What you need
to do is (approximately):

	dp = fetch(key);
	bcopy(offp, dp->d_data, sizeof(offp));
	lseek(fd, *offp, 0);

Declare offp so that it is guaranteed to be aligned, and copy all
pointers you wish to dereference into it before dereff'ing them.
