Crash in ink_freelist_new()
---------------------------
Key: TS-220
URL: https://issues.apache.org/jira/browse/TS-220
Project: Traffic Server
Issue Type: Bug
Affects Versions: 2.0.0a
Reporter: Leif Hedstrom
Priority: Critical
I got a bunch of core dumps similar to the one below (a few of the cores starts
in the #2 frame below). This is with the 2.0.0x branch, haven't seen it on
trunk at all.

I've also got a couple of stack traces like the below, I don't know if they are
related at all, but figured I'd include this in the same bug for now (since the
crash in both these traces are in ink_freelist_new(), just a completely
different stack trace).
