That's wrong because that would break the configure option --enable-minimal.
See also https://sourceforge.net/tracker/?group_id=12694&atid=312694 for a
proper patch.

What I see in the logs with both 5.7 and 5.6 after having applied the
aforementioned patch is:

injectHandler: injecting handler cache_handler into nsModuleTable

So iterator injection seems to work fine.

But I'm not sure that your claim is correct that the stash_cache is working
fine in 5.6 - a MIB walk times out at the end of the host resources MIB with
5.6:

$ agent/snmpd -Mmibs -c ../snmpd.conf -f -Lo
-DinjectHandler,helper:stash_cache,initialize_table_nsModuleTable :1161 &
[ ... ]
$ apps/snmpwalk -Mmibs -v2c -cpublic :1161 .1
[ ... ]
HOST-RESOURCES-MIB::hrSWRunPerfMem.32504 = INTEGER: 663508 KBytes
Timeout: No Response from :1161

The above test works fine with 5.4 and 5.5 however.
