I suspect the first complaint is about this bit in git head's
./src/bin/pg_dump/dumputils.c:
if (!parseAclItem(aclitems[i], type, name, subname, remoteVersion,
grantee, grantor, privs, privswgo))
return false;
since 'aclitems' isn't being freed before the return. And the second
complaint seems to concern parseAclItem() not freeing 'buf' when it
returns false. Both of these errors seem academic, since the callers
of buildACLCommands() will bail out with exit_horribly() or
exit_nicely() if it returns false. But IMO it's worth fixing anyway,
to keep the compilers happy or in case of future code calling
buildACLCommands() or parseAclItem().
Attached is a patch to hopefully fix those two errors. I couldn't
quite verify this fixes the OP's error messages, since "checker-266"
isn't done running make after several hours on this OS X machine.
