I had the same error: some website names couldn't be resolved by squid
and some of my ACL (mostly srcdom_regex) didn't work that good.
I tried to launch some lookup using "host" and figured that it was
definitively a dnsmasq issue.
I *suppressed* "127.0.0.1" from my resolv.conf i put my isp's DNS and
everything works fine. That's not a big issue for me because i mostly
use the DHCP side of dnsmasq.
I'm using Debian Sarge with Squid 2.5.14 compiled by hand and the
official debian package for dnsmasq, sorry i can't give more usable
information (maybe this is a negative-cache problem?).

tried remove 127.0.0.1 from /etc/resolv.conf. same problem.
so, the problem maybe not related to dnsmasq
tried insert my isp dns into squid.conf. problem still.
tried dns_children 32 but produce error?
try negative_dns_ttl 1 minutes. better result.
but sometimes still have to refresh to get the page displayed.
any better solution?
rgds,
