Hi,

since pvmpov still is version 3.1g from a FreeBSD port, I self-compiled
pvmpov 3.5. Unfortunately, this dumps core on my slave(s). I searched
for the reason and it turned out that the error occurs while trying to
init the display (which I thought I turned off by using -D on the
command line and Display=Off in global povray.ini).

The reason seems to be that ttyname(0) in unix.cpp's SVGAMode() returns
a NULL pointer (on FreeBSD 4.10-RELEASE-p3) which makes strstr() fail.
The attached patch checks for that so that I don't get coredumps anymore
and it works... ;-)
