Re: [SQU] Why a core dump in cache disk?

I hope you don't mind that I don't know anything about debugging... Here
is the info you requested.

It was compiled on OSF1's cc. Could compile it with gcc if thats better.
the version is: squid-2.3-200010300000

acl snmppublic snmp_community public
snmp_access allow snmppublic rubios # this is my box
snmp_access deny all

gdb output:
(gdb) up
#1 0x120018064 in aclMatchAcl (ae=0x14017e380, checklist=0x1) at
acl.c:1260
1260 acl.c: No such file or directory.
(gdb) print *ae
$1 = {name = "\027@\001", '\000' <repeats 12 times>,
"dstdoma\002\000\000\000\000\000\000", type = 1886741363,
  data = 0x63, cfgline = 0x0, next = 0x5}
(gdb) print *checklist
Cannot access memory at address 0x1.
(gdb) up

checklist=0x11fff7b90) at acl.c:1501

(gdb) print *list
$2 = {op = 1, acl = 0x14016b860, next = 0x14017e920}
(gdb) print *checklist
$3 = {access_list = 0x0, src_addr = {s_addr = 136708811}, dst_addr =
{s_addr = 0}, my_addr = {s_addr = 0}, my_port = 0,
  request = 0x0, conn = 0x0, ident = '\000' <repeats 63 times>, auth_user
= 0x0, state = {
    ACL_LOOKUP_NONE <repeats 24 times>}, snmp_community = 0x0, callback =
0, callback_data = 0x0}
(gdb)
