What's worse, test4 actually doesn't report any errors if any of the
cases would fail. You'd have to use a debugger to figure out what's
wrong.

Note that all of the cases you mention below actually clear the pointer
when the contents are freed, so this patch is still correctly handling
the memory.

Should I post another version where I add separate variables for any
reuse?
