Are you always building bytecode?  Which version of the
compiler, which operating system, and on which hardware
platform?  Does this happen when you compile for native code?

I suggest you also try copying the contents of core/lib/std.ml
into your empty module and bisecting to determine which
of the Core modules causes the failure.
