Public bug reported:
Using the latest autofs package (with libtirpc support) the automount
process crashes when mounting a nfs share (at least when using IPv4).
I am using a file /etc/auto.master.d/net.autofs to be able to mount
arbitrary nfs shares to /net:
/net -hosts -intr,soft --timeout=60
When trying to access a share (e.g. with the command "cd
/net/192.168.1.104" - using the hostname has the same effect) automount
crashes:
$ sudo systemctl stop autofs.service
$ source /etc/default/autofs
$ sudo gdb --args /usr/sbin/automount $OPTIONS -d -v -f
(gdb) run
[...]
attempting to mount entry /net/192.168.1.104

The segfault disappears if the autofs package is recompiled without
"--with-libtirpc" in debian/rules.
