Connected to host.somedomain.com. Escape character is '^]'. [ Trying mutual KERBEROS5 (host/host.somedomain.com@REALM)... ] zsh: bus error (core dumped) >Fix: Browsing around the sources reveals that there are multiple sources for function called 'net_write'. One is inside telnet application itself and has 2 parameters. Another is inside /usr/src/crypto/heimdal/lib/roken, which has 3 parameters. Original telnet sources with heimdal distribution seem to handle this by renaming the function in telnet from net_write to telnet_net_write, which seems to fix the core dump. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
