All newest official releases, AFAIK. ogdi-3.1.4, gdal 1.2.5 from source.
Debian/testing on intel P4.

renamed to /var/local/topodata/vmap0/, same error.

$ grep -rI "Illegal instruction" * 
in both GDAL and OGDI source dirs gives nothing..

Running it through the debugger shows this is as a SIGILL:
