Here's an update on this issue.

I re-did everything with Ocaml 4.01.0.  No difference.

Then I tried with a 64-bit Lubuntu virtual machine, set up identically to the 32-bit version (with Ocaml 4.00.1).   Then it worked.

So there seems to be some defect with some module (Zarith?) in a 32-bit environment, that only comes up in very specific situations like this one.

By the way, in the 64-bit linux, there was some problem with opam install building the documentation for Coq.  I removed the tex packages to avoid the documentation building altogether, but there does seem to be a little bug there that someone might need to fix.
