Is the code that contains the Runcode.run <your code> also compiled
with -rectypes?

Anyway, I think forcing recursive_types flag right before Runcode.run
may help. Here is how to do it, if ruiining at the top level:
 
#directory "INSTALLPREFIX/lib/ocaml/compiler-libs/";;
Clflags.recursive_types := true

If you compile the code first, then you need to add -I +compiler-libs
to the command line of the compiler. If the problem persists, it would
help to have a small test case.
