You don't. That is an internal compiler error.

Thanks for that, but since ast.m is not a standalone program, *and* it is being
compiled with intermodule optimization, it is not enough; we need either

- the whole program, i.e. all the .m files in the program, or
- ast.m, plus all the .int*, .opt and .trans_opt files of all the other modules
  in the program.

If you send that to us, I will take a look.

Zoltan.
