I have compiled GNU finger 1.37 using gcc on Solaris 2.1. fingerd
only lives for a limited time (seems to hang or dump core), after that
we get garbage user data like:
------------------------------------------------------------
% finger
/usr/local/etc/fingerdir/hostdata: file has not changed in 1 day, 13:16:39
User Real Name What Idle TTY Host Console Location
adminto 2:40 co rphc1a PHY 5.1.20
------------------------------------------------------------
Looking at the coredump gives:
------------------------------------------------------------
(gdb) file /usr/local/etc/fingerd
Reading symbols from /usr/local/etc/fingerd...done.
(gdb) core /core
Core was generated by `/usr/local/etc/fingerd'.
Program terminated with signal 11, Segmentation fault.

Thanks for any help.
