test make && make -C test/unit-testing/ dimassoc && (cd test/unit-testing && ./dimassoc; cd -) in smoke/dimassoc-pr1029. osnap_pt is wrong.

unknowns see DIMASSOC.zip

Doesnt parse. see the unit-tests and the pi logs

I am trying to test, but I was blocked by #1032

Yes, all >AC1018 are bad, condition with minimal length of item (35 bytes) to end of block is not working.
