[squid-users] 2.4 Stable1 SIGSEV, Segmentation fault

Hi,

    I have found a BUG in Squid 2.4Stable1, the HEAD branch from today
"squid-2.4-200103300000", after getting more than 300 req/s, thats bad,
because I cant load the server, I cant really get all from this hardware, Im
using FreeBSD4.2 RELEASE, the crash has the following message:

Program received signal SIGSEGV, Segmentation fault.
0x80aab9b in linklistPush (L=0x1fcfe7, p=0x502d0000) at tools.c:873
873 while (*L)

Below you can find the Backtrace of this crash:

P.S. If you need something else (patching, testing, root access, etc) , just
let me know (I can provide this because this is a testing server).

P.S.2 I can reproduce this in less than 1 minute, I have done it several
times, it alwas fails with the same error.

Greetings...
Ales
