Hi,

after a while (2~4h) chilli crash on my alpine linux router 2.1

Linux router 2.6.35.8-grsec #4-Alpine SMP Fri Nov 12 09:49:19 UTC 2010
i686 GNU/Linux

The program was compiled with the following options:

        ./configure --prefix=/usr \
                --sysconfdir=/etc \
                --mandir=/usr/share/man \
                --infodir=/usr/share/info \
                --localstatedir=/var/run/chilli \
                --libdir=/usr/lib \
                --sysconfdir=/etc \
                --with-openssl

This is the backtrace:

Core was generated by `/usr/sbin/chilli --pidfile=/var/run/chilli/chilli.pid'.
Program terminated with signal 11, Segmentation fault.
