Mail-list failed to send me the reply from Ion, attempting a reply anyways...
(mail-list owner, what i do wrong?)

Thanx Ion. I got it to work as you suggested.
Found old gtest - loggs that confirmed that the cache_last option wasn't needed in
old code so this must be a change .

Oh, and yes. uint64_t... :-)

.. yes I modified the code after cut-paste. The docs for 1.55 intrusive slist under
"Using base hooks" shows example with push_back() without mentioning cache_last. Mabey it should be push_front() in that example?


Nifty to get to pick and choose level of overhead :-)
