squid cores on exit so SMF complains on service disable

Sorry for the delay, I am just building 3.5.16 and see if that helps.
This will also include your patch.

Still the same:

Unfortunatly cores go away if compiled with
--disable-optimizations --disable-inline

It seems that the only working optimizing option is -Og, with all other squid core dumps.

It is a compiler error?

It seems this bug is fixed in squid-4 only. Bug 4438 (4405,4415,4435)
Do we bury squid 3.5?

That would be fine with me. There is already a squid-4.x branch which I prepared.

This seems to be fixed in 3.5.19,REV=2016.05.10 which I have rolled out and no problems any more.
