From poking around, I agree.  One particular error I noticed that
it makes a lot is that in a loop it says that an assigned value is
not referenced if the reference will not be hit until the next
iteration of the loop.

Cool.  I wasn't aware that anyone was already looking at this.

Agreed in general; however, with this 3.4 development build the
"Memory Error" section only showed two problems, and those were the
only two problems I found that were real.  It might be worth
monitoring that one section.

If nobody objects, I'll fix that small memory leak in the
regression test driver.  Hopefully someone more familiar with
pg_basebackup will fix the double-free (and related problems
mentioned by Tom) in streamutil.c.
