I prefer, when possible, to make sure that there's one and only one call
to free() in the code for a given block of memory. This makes it easier
to check that there is one and only execution of the free() call, for
each successful call to malloc(). This isn't always feasible - which is
a perfectly reasonable reason for using some other approach - but it's
trivially feasible in this case.
