I built squid as follows:

When running squid and attempting to get my client to use the squid
proxy, I see the following errors on the console of the squid machine:

I am running 3.HEAD-20080711. Any ideas why this is crashing?

Trying to get fakeauth to work with 3.x (have used 3.HEAD-20080711
sources), but I see crashes in fakeauth.
Anyone have this working?
Additionally, where is a definitive guide on getting NTLM auth to work
with 3.x? I have googled a bunch of 2.x stuff, but not much
mentioning 3.x
There is not much difference between 2.x and 3.x with regards to the
helpers. So it should not be crashing. Only one suspect change I can see...
Does this patch fix it?
