I just tried this. Bizarrely, top works fine when run through strace. I can
make the trace file available if anyone wants. Oh, and the original core
dump file too.

I doubt it. Both kernel and top are from the same stock RH7.0 distribution.

Yes, I am well aware of this... Hence why I verified my top binary against
an external, known, copy using md5 from my desktop, not from the server. :-)
