Dear XORP developers,

I'm unable to run XORP with a CVS compiled today. I get this :

I tried on two linux x86 machines without success (both debian).  I also
tried with gcc-2.95 instead of gcc-3.3.

My config2.boot is reduced to a minimum :
        interfaces {
       =20
            interface eth1 {
                description: "eth1"
                enabled: true
                /* default-system-config */
                vif eth1 {
                    enabled: true
                    address 10.2.0.2 {
                        prefix-length: 24
                        broadcast: 10.0.0.255
                        enabled: true
                    }
                }
            }
        }
       =20
        fea {
            enable-unicast-forwarding4: true
        }
       =20
My configure argurment is "--prefix $HOME/intel"
I'm not using anything weird and I haven't modified the code.

Any idea ?  Do I have a broken libc6 ?

------
Sidenote: when doing "make clean", fea/xorp_click_config_generator is
deleted because it is considered as a binary program in the Makefile.
So, I've got to "cvs up" before rebuilding the XORP tree...=20

Thanks,
