I have Ubuntu on a VPS (on Xen) and I'd like to install a Plan 9
server using 9vx. 9vx tip compiles, but segfaults after the "256M
memory" line (as does the precompiled binary, in the same place). I am
tunneling to local X11 on OS X 10.5.3.
I don't know how to debug this properly, but here is gdb output
similar to what I saw in another report.
Starting program: /home/tom/vx32/src/9vx/9vx -F -u glenda
