I want to use rsh to start povray on a remote machine, an intel Pentium
III, 1GHz, 512M ram, running linux 2.4.3aau4.
I am using povray 3.5.beta.RC5.

When I log in using rlogin and then start povray from the shell prompt
it works nicely, but when i start it directly using rsh:
rsh clusn2 ./povray +Ipovray35/scenes/advanced/skyvase.pov
it segfaults.

The problem seems to involve using SVGAlib for displaying,
but adding the flag -D does not help.

when I run:
rsh clusn2 strace ./povray +Ipovray35/scenes/advanced/skyvase.pov
I get:

(...)
write(2, "This copy expires in 3 day(s).\n", 31This copy expires in 3
day(s).
) = 31
write(2, "\n", 1
)                       = 1
ioctl(0, TCGETS, 0xbffffb90)            = -1 EINVAL (Invalid argument)
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++




using gdb:

rsh clusn2 gdb ./povray

(...)

(gdb) set args +Ipovray35/scenes/advanced/skyvase.pov
