Oh, yes, may be caused by other GET request fetching from cache or storing
to cache (doesn't happen wich cache disabled).
Perhaps you are bumping that
tunnel? Please note that you are not looking for the last request, but
for the request that triggered the assertion. It is very difficult to do
that with just ALL,2 and stripped executable, especially when you have
lots of concurrent transactions flying by.
No bumping. I can create unstripped executable (great if it works with
current core, but I may create new one).

I don't know where do those raise.c and raise.c belong (libthread? glibc?)
squid is stripped, i could probably compile it without stripping and re-try
Any ideas how to debug further? (disabling multi-cpu?)
