> The ACL file reading can trigger Windows Visual C++ consistency check on vector iterator decrement.
> Running the C++ test suite's acl_test starts a broker with options:
> --data-dir C:/qpid/trunk/build/src/tests/data_dir --acl-file policy.acl --auth no
> This policy.acl file contains only:
> acl allow all all
> This trips VC checks in qpid::acl::AclReader::loadDecisionData(boost::shared_ptr<qpid::acl::AclData> d={...}) because the 'for' loop at line 92:
> 	for (rlCitr i = rules.end() - 1; cnt; i--, cnt--) {
> tries to back i off the beginning of the vector.
