Re: [alpine-devel] Bug in rpc.mountd
I answered only to you, so I repost it to the ml.
bei:~# apk version 'libc0.9.32'
libc0.9.32-0.9.33.2-r1 = 0.9.33.2-r1
bei:~# cat /etc/apk/repositories
bei:~# uname -a
Linux bei 3.3.6-grsec #1-Alpine SMP Mon May 14 13:42:17 UTC 2012 x86_64 Linux
And yes it was working with the 2.4.1
The segfault happen when I try to mount the nfs share. I can let you
an SSH access if you want to check around my system.
Thanks for taking care of this problem.
