>Maybe newer GCC versions are causing trouble?

the 9vx that doesn't work for me is one that was compiled
over a year ago and has run happily on several Ubuntu and other
Linux versions until Ubuntu 10.04LTS. although i realise that
thanks to shared libraries, compiler variations could still play
a part, i'm still more inclined to suspect either a system-level
change, a difference of system configuration (eg, for shared libraries),
or a change to one of the supporting libraries, and there
are a few to choose from:
	linux-gate.so.1 =>  (0xb788d000)
	libX11.so.6 => /usr/lib/libX11.so.6 (0xb7785000)
	libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb776c000)
	libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7608000)
	libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb75ee000)
	libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb75ea000)
	/lib/ld-linux.so.2 (0xb788e000)
	libXau.so.6 => /usr/lib/libXau.so.6 (0xb75e6000)
	libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb75e1000)

9vx also makes inventive use of mmap and sigsegv.
