I am able to repro this and it seems to have changed in behavior in the last build. Something might have happened when we added a new option.

I've figured out the problem. It is a buffer overrun when we tried to print -idic_exclusiveto. The buffer size of write_printf is 128 whereas -idic_exclusiveto is 142 characters (not including the null-terminator). A temporary workaround would be to make the buffer larger or reduce the number of characters in it, but I feel like we should have a more scalable solution.
