We had a recent report of strange server-side behavior on AIX that went
away after rebuilding with a newer version of xlc, suggesting that the
code was getting bitten by an xlc optimization bug.  Perhaps this is the
same thing inside pg_dump.  If you're not using the latest xlc, try
updating.  If you are, does rebuilding with -O0 change the behavior?
