Hello,

I've compiled vdr on alpinelinux 2.5.0 and get a segfault during
start of vdr.
Even without plugins I get this segfault (I didn't apply any patch to
vdr sources).
Vdr was started with the command:

/usr/local/bin/vdr --config=/etc/vdr --epgfile=/tmp/epg.data --grab=/dev/shm --log=3.1 --mute --no-kbd --user=root --video=/remote/vdr/

I've made a backtrace with gdb:

I do not get viruses because I do not use MS software.
If you use Outlook then please do not put my email address in your
address-book so that WHEN you get a virus it won't use my address in the
