Hi Amos, I now explicitly enabled --enable-stacktraces Enable automatic call backtrace on fatal errors during the build and added CFLAGS="-g -ggdb" in front of ./configure but the result seems to be the same... # ./squid -v Squid Cache: Version 3.1.0.11 configure options: '--prefix=/opt/squid-3.1.0.11' '--enable-icap-client' '--enable-ssl' '--enable-linux-netfilter' '--disable-ipv6' '--disable-translation' '--disable-auto-locale' '--with-pthreads' '--with-filedescriptors=32768' '--enable-stacktraces' 'CFLAGS=-g -ggdb' --with-squid=/usr/local/src/squid-3.1.0.11 --enable-ltdl-convenience 2009/07/21 15:43:50| assertion failed: mem.cc:236: "size == StrPoolsAttrs[i].obj_size" Aborted # gdb --args ./squid -NCXd9 GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

There are many ways to run stuff with gdb. The one I gave was simply the easiest to instruct. The way you just did was another. I think the "no stack" is probably the lack of debug symbols in your build. You will need to check/fix that before we can continue. I don't know how you build Squid so can't help with this bit I'm sorry. Amos
