So I already did that. In fact, I already piped the code through GCC
to find what the problem is, and GCC liked it just fine. I'm pasting
the repro case below. Note that blind random fiddling found that removing
the (redundant) "virtual" from the declaration of Derived::someFunction
will avoid the internal compiler error, although it took quite a while to
get to that point from the initial C1001.

Also, I tried to report this simple repro case on the MSDN LadyBug site,
but it appears they don't accept bug reports for their currently active
released products (MSVC 2003) -- only for their current beta 2005. I'm
not about to download and install a beta product just to report a bug I've
found in their shipped product, because I'm trying to get MY job done, not
theirs. I find their approach to customer support more than a little
arrogant in cases like these...

Cheers,
