Bug#715569: Official mod_vroot lib broken, lib built from source works

[votdev]

I can confirm this too on an amd64 system. Rebuilding package from
source makes the mod_vroot plugin working. I suggest to rebuild the
package for the next Wheezy dot-release. It is really sad to see that
this is not fixes since Wed, 10 Jul 2013, because it's so simple to fix.

Config:

DebugLevel 10
DefaultRoot /srv/ftp
<IfModule mod_vroot.c>
  VRootEngine on
  VRootOptions allowSymlinks
  VRootLog /var/log/proftpd/vroot.log
  VRootAlias /tmp/xyz/test3 test3
</IfModule>



The daemon segfaults with the original Debian package 0.9.2-2+b2.

Rebuilding the package from the original Debian sources

proftpd-mod-vroot_0.9.2-2.dsc
proftpd-mod-vroot_0.9.2.orig.tar.gz
proftpd-mod-vroot_0.9.2-2.debian.tar.gz

fixes the problem.
