>Description:

I have a five dial-in lines. Sometimes login core dumps:

Jul 29 15:10:15 relay /kernel: pid 12953 (login), uid 0: exited on signal 3 (core dumped)

I have recompiled login statically, and installed it non-stripped.
Here is GDB output of the latest two cores:

Core was generated by `login'.
Program terminated with signal 3, Quit.
